Question
A and B entered into a business investing Rs. (x + 75)
and Rs. (x – 55) respectively. After one year they invested Rs. 120 more and Rs. 200 more respectively. After 2 years, ratio of the profit shares of A to B is 7:6. Find the value of x.Solution
Ratio of profit share of A to B = [x + 75 + x + 75 + 120]:[x – 55 + x – 55 + 200] = [2x + 270]:[2x + 90] According to question; (2x + 270)/(2x + 90) = 7/6 => 12x + 1620 = 14x + 630 => 2x = 990 => x = 495
