Given the following coded blood relationship definitions:
- $A \star B$ means ' $A$ is the mother of $B$ '
- $A \sharp B$ means ' $A$ is the brother of $B$ '
- $A \dagger B$ means ' $A$ is the daughter of $B$ '
- $A \Delta B$ means ' $A$ is the father of $B$ '

Based on the expression $K \star L \sharp M \dagger N \Delta P$ , how is $P$ related to $K$ ?

Son

Daughter

Mother

Cannot be determined

Cevabı ve açıklamayı göster

Cevap: Cannot be determined

Cevap

Cannot be determined (the person is either the son or the daughter)

Deconstructing the relation expression shows that

K

(mother) and

N

(father) are married parents of

L

,

M

, and

P

. Because no operator defines whether

P

is male or female,

P

could be either a son or a daughter of

K

. Therefore, the exact relation cannot be determined uniquely.

Adım Adım Çözüm

1

Decode the first part of the expression:

K \star L \sharp M

K

is the mother of

L

, and

L

is the brother of

M

. Therefore,

K

is the mother of both

L

and

M

.

Siblings share the same parents.

2

Decode the next part:

M \dagger N

M

is the daughter of

N

. Since

K

is already established as the mother of

M

,

N

must be the father of

M

(and husband of

K

).

A child has one male parent (father) and one female parent (mother).

3

Decode the final part:

N \Delta P

N

is the father of

P

. Since

N

and

K

are the parents of

L

and

M

,

P

is also a child of

K

and

N

.

Children of the same father belong to the same sibling group.

4

Determine the gender of

P

The operator

\Delta

indicates that

N

is the father of

P

, but gives no information regarding

P

's gender.

P

can be male or female.

Gender must be explicitly stated and cannot be assumed.

A field researcher starting at a base station walks $15\text{ km}$ towards the North. He then turns $135^\circ$ clockwise and walks $8\sqrt{2}\text{ km}$ . Next, he turns $90^\circ$ counter-clockwise and walks $7\sqrt{2}\text{ km}$ . From this location, he turns West and walks $3\text{ km}$ , and finally turns South and walks $9\text{ km}$ to reach an observation post. What is the shortest straight-line distance (in km) between the observation post and the base station?

Cevabı ve açıklamayı göster

Cevap: 13

Cevap

The shortest straight-line distance between the observation post and the base station is

13\text{ km}

.

Resolving each directional segment into horizontal and vertical components gives a net final coordinate of

(12, 5)

relative to the starting origin

(0, 0)

. Applying the Pythagorean theorem

\sqrt{12^2 + 5^2} = \sqrt{169} = 13\text{ km}

yields the exact straight-line distance.

Adım Adım Çözüm

1

Represent the trajectory using 2D coordinate vectors starting from origin (0, 0).

Initial position = (0, 0). After moving 15 km North, position = (0, 15).

North movement aligns with the positive y-axis.

2

Decompose the 135-degree clockwise turn vector (South-East displacement).

Displacement is (+8, -8), placing the researcher at (8, 7).

A 135-degree clockwise turn from North faces South-East (45 degrees below positive x-axis).

3

Decompose the 90-degree counter-clockwise turn vector (North-East displacement).

Displacement is (+7, +7), placing the researcher at (15, 14).

A 90-degree counter-clockwise turn from South-East faces North-East (45 degrees above positive x-axis).

4

Apply cardinal direction adjustments for West and South movements.

Moving 3 km West and 9 km South gives final coordinates (12, 5).

West subtracts from x-coordinate, and South subtracts from y-coordinate.

5

Calculate net displacement using Pythagorean theorem.

Distance = sqrt(12^2 + 5^2) = 13 km.

The direct line between (0, 0) and (12, 5) forms a right-angled triangle with sides 12 and 5.

In a certain code language, the word RESOLUTE is written as KHJRQXIH. Based on the exact same transformation logic, how is the word DYNAMICS written in that code language?

YBODPLZV

FBPDOLEV

WBMDNLXV

GDQBPTFJ

Cevabı ve açıklamayı göster

Cevap: YBODPLZV

Cevap

The coded representation for DYNAMICS is YBODPLZV.

The code follows a dual position-dependent rule: odd-numbered positions are converted to their reverse alphabetical letter (

A=1 \leftrightarrow Z=26

) and then shifted forward by 2 positions, whereas even-numbered positions are shifted forward by 3 positions. Applying this systematically to DYNAMICS yields YBODPLZV.

Adım Adım Çözüm

1

Analyze the transformation rule in RESOLUTE -> KHJRQXIH by indexing positions 1 to 8

Letters at odd positions (1, 3, 5, 7) undergo reverse alphabetical transformation (

A \leftrightarrow Z

) followed by a forward shift of

+2

. Letters at even positions (2, 4, 6, 8) undergo a standard forward shift of

+3

.

Deconstructing position-dependent rules is necessary to establish the coding algorithm.

2

Apply the odd-position transformation (Reverse Letter + 2) to DYNAMICS

1st letter D (4) -> Reverse W (23) + 2 = Y; 3rd letter N (14) -> Reverse M (13) + 2 = O; 5th letter M (13) -> Reverse N (14) + 2 = P; 7th letter C (3) -> Reverse X (24) + 2 = Z.

Odd positions follow reverse alphabetical indexing with a shift offset.

3

Apply the even-position transformation (Forward Shift + 3) to DYNAMICS

2nd letter Y (25) + 3 = B; 4th letter A (1) + 3 = D; 6th letter I (9) + 3 = L; 8th letter S (19) + 3 = V.

Even positions advance by 3 alphabetical steps.

4

Combine the resulting transformed letters in sequence

Pos 1 to 8: Y - B - O - D - P - L - Z - V.

Assembling the position results forms the complete final coded word YBODPLZV.

At sunrise, an environmental officer stands facing her own shadow. She then executes the following sequence of movements:
1. She turns $135^\circ$ anti-clockwise and walks $10\sqrt{2}\text{ m}$ .
2. She turns $90^\circ$ to her right and walks $6\sqrt{2}\text{ m}$ .

Cevabı ve açıklamayı göster

Cevap: $15\text{ m}$ , North-East

Cevap

15\text{ m}

in the North-East direction

At sunrise, a person facing her shadow faces West. Executing the four angular turns results in successive vectors:

(10, 10)

North-East,

(6, -6)

South-East,

(0, 15)

North, and

(-7, -7)

South-West. Summing these vector components gives a net East-West displacement of

X = 9\text{ m}

East and a net North-South displacement of

Y = 12\text{ m}

North. Using the Pythagorean theorem, the direct distance is

\sqrt{9^2 + 12^2} = 15\text{ m}

in the North-East quadrant.

Adım Adım Çözüm

1

Determine initial facing direction

Facing West (

180^\circ

)

At sunrise, the Sun is in the East, so shadows fall toward the West. Facing her own shadow means she initially faces West.

2

Calculate vector displacement for Movement 1

Direction: North-East (

45^\circ

), Vector:

(+10, +10)

From West (

180^\circ

), turning

135^\circ

anti-clockwise gives

180^\circ - 135^\circ = 45^\circ

(North-East). Displacement

= (10\sqrt{2}\cos 45^\circ, 10\sqrt{2}\sin 45^\circ) = (10, 10)

.

3

Calculate vector displacement for Movement 2

Direction: South-East (

315^\circ

), Vector:

(+6, -6)

From North-East (

45^\circ

), turning

90^\circ

right (clockwise) gives

45^\circ - 90^\circ = -45^\circ = 315^\circ

(South-East). Displacement

= (6\sqrt{2}\cos 315^\circ, 6\sqrt{2}\sin 315^\circ) = (6, -6)

.

4

Calculate vector displacement for Movement 3

Direction: North (

90^\circ

), Vector:

(0, +15)

From South-East (

-45^\circ

), turning

135^\circ

left (anti-clockwise) gives

-45^\circ + 135^\circ = 90^\circ

(North). Displacement

= (0, 15)

.

5

Calculate vector displacement for Movement 4

Direction: South-West (

225^\circ

), Vector:

(-7, -7)

From North (

90^\circ

), turning

135^\circ

left (anti-clockwise) gives

90^\circ + 135^\circ = 225^\circ

(South-West). Displacement

= (7\sqrt{2}\cos 225^\circ, 7\sqrt{2}\sin 225^\circ) = (-7, -7)

.

6

Sum total net displacement

(X, Y)

and find direct distance and final cardinal direction

X = 9\text{ m}

East,

Y = 12\text{ m}

North; Distance

= 15\text{ m}

, Direction = North-East

Total East displacement

X = 10 + 6 + 0 - 7 = 9\text{ m}

. Total North displacement

Y = 10 - 6 + 15 - 7 = 12\text{ m}

. Direct distance

= \sqrt{9^2 + 12^2} = \sqrt{81 + 144} = \sqrt{225} = 15\text{ m}

. Since both

X > 0

and

Y > 0

, the final direction relative to the start is North-East.

Cevabı ve açıklamayı göster

Cevap: T15I

Cevap

T15I

The correct term is obtained by independently evaluating the three sub-series: first letters advance by

+2

(

P, R, T, V, X

), central numbers increment by expanding step differences of

+4, +8, +12, +16

(

3, 7, 15, 27, 43

), and third letters advance by

+3

(

C, F, I, L, O

). Unifying these components produces

T15I

.

Adım Adım Çözüm

1

Analyze the pattern of the first letter in each term

The first letters follow an increasing positional shift of

+2

:

P(16) \xrightarrow{+2} R(18) \xrightarrow{+2} T(20) \xrightarrow{+2} V(22) \xrightarrow{+2} X(24)

. Thus, the missing first letter is

T

.

Tracking alphabet positional values reveals a constant linear addition of 2 units.

2

Analyze the pattern of the central numerical values

The differences between consecutive numbers form a sequence of multiples of

4

:

7 - 3 = 4

, so the next difference is

4 + 4 = 8

, giving

7 + 8 = 15

. Verifying subsequent terms:

15 + 12 = 27

and

27 + 16 = 43

. Thus, the missing number is

15

.

The number sequence follows an increasing double-difference pattern where each term's increment grows by

+4

.

3

Analyze the pattern of the third letter in each term

The third letters follow an increasing positional shift of

+3

:

C(3) \xrightarrow{+3} F(6) \xrightarrow{+3} I(9) \xrightarrow{+3} L(12) \xrightarrow{+3} O(15)

. Thus, the missing third letter is

I

.

Tracking alphabet positional values reveals a constant shift of 3 steps forward.

4

Combine the results of all three components

Combining the first letter

T

, middle number

15

, and third letter

I

yields the complete term

T15I

.

Each element operates independently according to its own sub-rule.

Cevap: The total number of trainees enrolled in exactly one training module is $80$ .; The total number of trainees enrolled in at least two training modules is $55$ .

Cevap

The statements asserting that

80

trainees are enrolled in exactly one training module and that

55

trainees are enrolled in at least two training modules are correct.

The correct evaluation shows that exactly one module enrollment totals

35 + 20 + 25 = 80

, and at least two modules enrollment totals

45 + 10 = 55

.

Adım Adım Çözüm

1

Identify the region for trainees taking all three modules.

n(A \cap B \cap C) = 10

.

This fundamental triple intersection value must be subtracted from pairwise intersections to isolate dual-module regions.

2

Calculate trainees enrolled in exactly two modules.

Only

A \text{ and } B = 30 - 10 = 20

; Only

B \text{ and } C = 25 - 10 = 15

; Only

A \text{ and } C = 20 - 10 = 10

. Total taking exactly two modules =

20 + 15 + 10 = 45

.

Subtracting the triple intersection isolates individuals taking exclusively two subjects.

3

Calculate trainees enrolled in exactly one module.

Only

A = 75 - (20 + 10 + 10) = 35

; Only

B = 65 - (20 + 15 + 10) = 20

; Only

C = 60 - (10 + 15 + 10) = 25

. Total taking exactly one module =

35 + 20 + 25 = 80

.

Subtracting dual and triple overlaps from total single set numbers yields single-module counts.

4

Determine total trainees taking at least one module and trainees taking none.

Total taking at least one module

= 80 \text{ (single)} + 45 \text{ (double)} + 10 \text{ (triple)} = 135

. Trainees taking none

= 150 - 135 = 15

.

Applying set summation gives total enrolled trainees, from which the non-enrolled count is derived.

B corresponds to Son of A; D corresponds to Wife of A; E corresponds to Grandson of A; and F corresponds to Granddaughter of A.

Each member is mapped according to explicit generation depth and gender: D is the female spouse (Wife of A), B is the male child (Son of A), E is the child of daughter C (Grandson of A), and F is the female child of son B (Granddaughter of A).

Adım Adım Çözüm

1

Determine the relationship between A and D

Since A and D are married and A is male, D is female and is the Wife of A.

Marriage establishes a spouse relationship between A and D.

2

Determine the relationship of B to A

B is a male child of A and D, so B is the Son of A.

Direct male offspring of a parent is a son.

3

Determine the relationship of E to A

C is the female child (daughter) of A, and E is the male child (son) of C. Thus, E is the Grandson of A.

A child's child represents the grand-generation, specifically maternal grandson here.

4

Determine the relationship of F to A

B is the son of A, and F is the female child (daughter) of B. Thus, F is the Granddaughter of A.

A son's daughter is a paternal granddaughter.

In a certain coding system, vowels are replaced by their reverse alphabetical position letters ( $A \leftrightarrow Z$ , $E \leftrightarrow V$ , $I \leftrightarrow R$ , $O \leftrightarrow L$ , $U \leftrightarrow F$ ). Consonants appearing at odd-numbered position indices (1st, 3rd, 5th, etc.) are shifted forward by $3$ positions in the alphabet ( $+3$ ), while consonants appearing at even-numbered position indices (2nd, 4th, 6th, etc.) are shifted backward by $2$ positions ( $-2$ ).

For example, under this system, the word BASKET is coded as EZVIVR.

What is the coded representation for the word HARVEST?

Cevabı ve açıklamayı göster

Cevap: KZUTVQW; kzutvqw

Cevap

KZUTVQW

Transforming each letter of HARVEST according to its position and type yields: Position 1 (H, odd-index consonant)

\rightarrow

H

+ 3 = \mathbf{K}

; Position 2 (A, vowel)

\rightarrow

reverse of A

= \mathbf{Z}

; Position 3 (R, odd-index consonant)

\rightarrow

R

+ 3 = \mathbf{U}

; Position 4 (V, even-index consonant)

\rightarrow

V

- 2 = \mathbf{T}

; Position 5 (E, vowel)

\rightarrow

reverse of E

= \mathbf{V}

; Position 6 (S, even-index consonant)

\rightarrow

S

- 2 = \mathbf{Q}

; Position 7 (T, odd-index consonant)

\rightarrow

T

+ 3 = \mathbf{W}

. Concatenating these transformed letters produces KZUTVQW.

Adım Adım Çözüm

1

Analyze the position index (1 to 7), letter type (vowel or consonant), and index parity (odd or even) for each letter in HARVEST.

H (1st, odd consonant), A (2nd, vowel), R (3rd, odd consonant), V (4th, even consonant), E (5th, vowel), S (6th, even consonant), T (7th, odd consonant).

Establishing individual letter rules based on position and character type is required before transformation.

2

Apply

+3

shift to odd-positioned consonants (H, R, T).

H (8) + 3 = 11 (K); R (18) + 3 = 21 (U); T (20) + 3 = 23 (W).

Consonants at positions 1, 3, and 7 move forward by 3 letters in the alphabet.

3

Apply reverse alphabetical indexing to vowels (A, E).

A (1st letter) becomes Z (26th letter); E (5th letter) becomes V (22nd letter).

Vowels map to their opposite position pairs (

27 - \text{position}

).$

4

Apply

-2

shift to even-positioned consonants (V, S).

V (22) - 2 = 20 (T); S (19) - 2 = 17 (Q).

Consonants at positions 4 and 6 move backward by 2 letters in the alphabet.

5

Combine the transformed letters sequentially from positions 1 through 7.

K + Z + U + T + V + Q + W = KZUTVQW.

Assembling the converted characters in original sequence yields the final coded string.

A1441E

The correct term is determined by combining three distinct concurrent rules: the first letter shifts forward by incrementally larger intervals (+3, +4, +5, +6, +7) wrapping from T to A; the middle number follows the operational recurrence relation (Previous × n) - (n - 1) yielding (241 × 6) - 5 = 1441; and the third letter shifts backward by expanding steps (-2, -3, -4, -5, -6) moving from K to E.

Adım Adım Çözüm

1

Analyze the pattern of the first letters in the terms: B, E, I, N, T

Positions in alphabet: B(2) → (+3) → E(5) → (+4) → I(9) → (+5) → N(14) → (+6) → T(20). The next shift must be +7. T(20) + 7 = 27, which wraps around to A(1).

The forward positional shift increases by +1 at each successive step.

Analyze the pattern governing the letter component of the series.

Positions in the English alphabet: B is 2, E is 5, I is 9, N is 14, T is 20.
Differences between consecutive letter positions:

5 - 2 = +3

9 - 5 = +4

14 - 9 = +5

20 - 14 = +6

Following this progression, the next shift must be

+7

.

The numerical terms are 4, 9, 19, 39, 79.
Evaluating the relation between consecutive terms:

4 \times 2 + 1 = 9

9 \times 2 + 1 = 19

19 \times 2 + 1 = 39

39 \times 2 + 1 = 79

Applying the same rule to 79:

79 \times 2 + 1 = 159

.

Each number is generated by doubling the preceding number and adding 1.
