Difficulty: EasyBasic Ratios

A military logistics unit is preparing a supply drop. The standard loadout requires a ratio of 22 pallets of Meals Ready-to-Eat (MREs) for every 33 pallets of bottled water. If the unit loads 3030 pallets of MREs, how many pallets of bottled water are required for the drop?

  3. C
    1818
  4. D
    7575

Answer

The correct answer is 4545 pallets of bottled water.
The correct answer is calculated by setting up a proportion based on the part-to-part ratio. The MREs represent 22 parts of the ratio, which equals 3030 pallets. Therefore, one part equals 1515 pallets. The water represents 33 parts, so 3×15=453 \times 15 = 45 pallets of water.

Step-by-Step Solution

1
Identify the given ratio and known quantity.
The ratio of MREs to water is 2:32:3, and there are 3030 pallets of MREs.
Establishing the relationship between the parts is necessary to find the unknown quantity.
2
Determine the multiplier for the ratio.
30÷2=1530 \div 2 = 15
Since the 22 parts in the ratio represent 3030 actual pallets, dividing determines the value of one part.
3
Calculate the unknown quantity using the multiplier.
3×15=453 \times 15 = 45
Multiplying the water ratio (33) by the value of one part (1515) gives the actual number of water pallets.
