A and B started a business in partnership investing Rs. 20,000 and Rs. 15,000 respectively. After six months, C joined them with Rs. 20,000. What will be B’s share in the total profit of Rs. 25,000 earned at the end of 2 years from the starting of the business?

A. Rs. 7500
B. Rs. 9000
C. Rs. 9500
D. Rs. 10,000
E. None of these

Explanation :

A : B : C = (20000 x 24) : (15000 x 24) : (20000 x 18)
              = 4 : 3 : 3.

B's share = Rs. (25000 x 3/10)
               = Rs. 7500.
