1. Subhash starts a business by investing Rs. 25000. 6 months later Aditya joins him by investing Rs. 15000. After another 6 months Aditya invests an additional amount of Rs. 15000. At the end of 3 years they earn a profit of Rs. 247000. What is Aditya's share in the profit ?

A. Rs. 105000

B. Rs. 111500

C. Rs. 123000

D. Rs. 130000

Solution:

\begin{aligned} Subhas : Aditya \\ = (25000 \times 36) : (15000 \times 6 + 30000 \times 24) \\ = 900000 : 810000 \\ = 10 : 9 \\ ∴ Aditya's share \\ \Rightarrow Rs . (247000 \times \frac{9}{19}) \\ \Rightarrow Rs .117000 \end{aligned}
