A, B and C start a business. A invests 2 times as much as B invest. B invests \(\frac{3}{4}\)th of what C invests. At the end of year they get Rs.7800 as a profit. Find B’s share in the profit.

1800

           A   :   B   :   C

Inv.⇒   2   :  1

                   3   :    4

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

⇒         6  :  3    :   4

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

Profit:  6  :  3    :   4    =   13R

13R = 7800

1R = 600

B's Profit = 3R = 3 × 600 = 1800
