1. Arun started a business investing Rs. 38000. After 5 months Bakul joined him with a capital of Rs. 55000. At the end of the year the total profit was Rs. 22000. What is the approximate difference between the share of profits Arun and Bakul ?

A. Rs. 1007

B. Rs. 1192

C. Rs. 1568

D. Rs. 1857

Solution:

\begin{aligned} Arun : Bakul \\ = (38000 \times 12) : (55000 \times 7) \\ = 456000 : 385000 \\ = 456 : 385 \\ ∴ Required difference \\ = Rs . [22000 \times (\frac{456}{841} - \frac{385}{841})] \\ = Rs . (22000 \times \frac{71}{841}) \\ = Rs. 1857 .31 \\ = Rs. 1857 \end{aligned}
