A, B and C start a business. A invests 3 times as much as B invest. B invests \(\frac{2}{3}\) rd of what C invests. At the end of year they get Rs. 6600 as a profit. Find B’s share in the profit.

Rs. 1200

           A   :   B   :   C

Inv.⇒   3   :  1

                   2   :    3   

⇒         6  :  2    :   3

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

Profit:  6  :  2    :   3    =   11R

11R = 6600

1R = 600

B's Profit = 2R = 2 × 600 = 1200
