A and b entered into partnership with capital in the ratio 4:5 after 3 months a withdraw 1/4 of his capital and b withdraw 1/5 of his capital they gain at the end of 10 months was rs 760 a's share is this profit is

Answer 1

Let their initial capitals be 4x and 5x.
After 3 months A withdrew (1/4)*4x = x and B withdrew (1/5)*5x = x.
Therefore Ratio of capitals = (4x*3 + 3x*7 : 5x*3 + 4x*7)
= 33x : 43x = 33:43 
A's share = Rs.(760 * 33/76) = Rs. 330
