Question
A and B entered into a business investing Rs. (x + 45)
and Rs. (x β 55) respectively. After one year they invested Rs. 70 more and Rs. 140 more respectively. After 2 years, ratio of the profit shares of A to B is 6:5. Find the value of x.Solution
Ratio of profit share of A to B = [x + 45 + x + 45 + 70]:[x β 55 + x β 55 + 140] = [2x + 160]:[2x + 30] According to question; (2x + 160)/(2x + 30) = 6/5 => 10x + 800 = 12x + 180 => 2x = 620 => x = 310
