Difficulty: MediumRatio, Proportion, and Rate

Three business partners, XX, YY, and ZZ, invest in a venture. XX contributes 13\frac{1}{3} of the total capital for 14\frac{1}{4} of the total duration of the business. YY contributes 14\frac{1}{4} of the capital for 12\frac{1}{2} of the duration, while ZZ contributes the remaining capital for the entire duration. If the total profit realized from the business is N78,000\mathcal{N}78,000, what is ZZ's share of the profit?

  1. A
    N32,500\mathcal{N}32,500
  2. B
    N26,000\mathcal{N}26,000
  3. N52,000\mathcal{N}52,000Answer
  4. D
    N60,000\mathcal{N}60,000

Answer

N52,000\mathcal{N}52,000
Profit distribution in compound partnerships depends on both capital invested and investment time duration. XX's product is 112\frac{1}{12}, YY's product is 18\frac{1}{8}, and ZZ's product is 512\frac{5}{12}. Scaling these by 24 gives a ratio of 2:3:102 : 3 : 10. With 15 total parts, ZZ receives 1015\frac{10}{15} of N78,000\mathcal{N}78,000, which equals N52,000\mathcal{N}52,000.

Step-by-Step Solution

1
Determine ZZ's fraction of the total capital
ZZ's capital fraction =1(13+14)=1712=512= 1 - \left(\frac{1}{3} + \frac{1}{4}\right) = 1 - \frac{7}{12} = \frac{5}{12}
The sum of all capital contributions must equal 1.
2
Calculate the compound product of (Capital Share ×\times Time Duration) for each partner
X=13×14=112X = \frac{1}{3} \times \frac{1}{4} = \frac{1}{12}, Y=14×12=18Y = \frac{1}{4} \times \frac{1}{2} = \frac{1}{8}, Z=512×1=512Z = \frac{5}{12} \times 1 = \frac{5}{12}
Profit sharing in compound partnerships is proportional to the product of capital invested and the time period.
3
Convert the fractions to an equivalent integer ratio
Multiplying 112:18:512\frac{1}{12} : \frac{1}{8} : \frac{5}{12} by 24 gives the ratio 2:3:102 : 3 : 10
Finding the least common multiple (24) simplifies the fractions into integer ratio parts.
4
Compute ZZ's profit share from the total profit
Total ratio parts =2+3+10=15= 2 + 3 + 10 = 15. ZZ's share =1015×N78,000=N52,000= \frac{10}{15} \times \mathcal{N}78,000 = \mathcal{N}52,000
Multiply total profit by ZZ's ratio fraction.
