A and B are partners in a business. A contributes 1/4 of the capital for 15 months and B received 2/3 of the profit. For how long Bs money was used ?

Let the total profit be Rs. z. Then, Bs share = Rs. 2z/3, As share = Rs. ( z - 2z/3 ) = Rs. z/3. A : B = z/3 : 2z/3 = 1:2 Let the total capital be Rs, X and suppose Bs money was used for x months. Then. (1(x) / 4 * 15) / (3x) / 4 * y) = 1/2 <=> y = (15 * 2 / 3) = 10 . Thus, Bs money was used for 10 months.
