A, B and C start a business. A invests 4 times as much as B invest. B invests \(\frac{2}{5}\)th part of what C invests. At the end of year they get Rs.7500 as a profit. Find C’s share in the profit.

2500

           A   :   B   :   C

Inv.⇒   4   :  1

                   2   :    5

----------------------------------    

⇒         8  :  2    :   5

*If time is same then investment ratio becomes profit ratio*

Profit:  8  :  2    :   5    =   15R

15R = 7500

1R = 500

C's Profit = 5R = 5 × 500 = 2500
