A and B together start a business with investment of Rs. 1600 and Rs. (x + 600), respectively. If the profit earned after 5 years is Rs. 6000 and share of A is Rs. 2500, then find the value of x.
Ratio of share of profit of A : B = 1600: (x + 600) So, {1600/(x + 2200)} × 6000 = 2500 => 3840 = x + 2200 => x = 1640
