A & B partner in a business , A contribute 1/4 of the capital for 15 months & B received 2/3 of the profit . For how long B’s money was used
Answer: C
B received 2/3 of the profit
A : B = 1 : 2
Let the total capital = x
Then A’s capital = x/4 B’s capital = x – x/4 = 3x/4
If B’s money was used for a months Then A : B = (x/4)*15 : (3x/4)*a = 1 : 2
15/4 : 3b/4 = 1 : 2
15 : 3b = 1 : 2
5 : b = 1 : 2
a = 5*2 = 10
