Question
P and Q started a business by investing Rs.5600 and
Rs.4000 respectively. After 4 months, Q increased his investment by a certain percentage such that at the end of 1 year, the profit shares of P and Q were equal. By how much percentage did Q increased his investment?Solution
Let the increased investment amount of Q = Rs.x Ratio of profit shares of P and Q = (5600 x 12) : (4000 x 4 + 8y) = 1:1 So, 67200 = 24000 + 8x => x = 5400 Increase in investment of Q = 5400 – 4000 = Rs.1400 Required % = (1400/4000) x 100 = 35%
