Question
A and B entered into a business investing Rs. (x + 70)
and Rs. (x – 50) respectively. After one year they invested Rs. 60 more and Rs. 120 more respectively. After 2 years, ratio of the profit shares of A to B is 9:8. Find the value of x.Solution
Ratio of profit share of A to B = [x + 70 + x + 70 + 60]:[x – 50 + x – 50 + 120] = [2x + 200]:[2x + 20] According to question; (2x + 200)/(2x + 20) = 9/8 => 16x + 1600 = 18x + 180 => 2x = 1420 => x = 710
