If the ratio of time periods of investment of A and B is 2:5, profit at the end of the year is Rs.140000 and A’s share in it is Rs.40000, then what is the ratio of A’s and B’s investment?
Let the ratio of A’s and B’s investment be x:y. The ratio of time periods of investment of A, => [2x/(2x+5y)] x 140000 = 40000 => [2x/(2x+5y)] = 2/7 => 14x = 4x + 10y => 10x = 10y => x:y = 1:1
