Ravi and Ramu are partners in a business.Ravi contributes 1/6 of the capital for 16 months and Ramu received 2/3 of the profit. For how long Ramu's money was used ?
Select
A) 7 months	B) 6 months	C) 3 months	D) 8 months	E) 9 months
Let the total Profit be Z.   Ramu's profit share is 2/3 of profit (i.e 2Z/3)   Ravi's profit is (Z-2Z/3) =Z/3   Hence the profit ratio is , Ravi : Ramu = Z/3 : 2Z/3 = 1:2   Let total Capital be Rs.X and Ramu has contributed for Y months.Since Ramu's profit share is 2/3, his invest share will be 2/3 in capital.   Ravi's invest for 16 months / Ramu's invest for Y months = Ravi's profit share / Ramu's profit share   i.e. (X/6 x 16) / (2X/3 x Y) = 1/2   Solving the above equation, we get Y = 8.   So Ramu's money has been used for 8 months.   Answer: 8 months
