Question
M and N started a business by investing Rs.5500 and
Rs.6500 respectively. After 6 months, M and N increased their investments by 40% and Rs.2400 respectively. The annual profit share of N was Rs.2100. Find the total annual profit received by them together.Solution
Increased investment of M = 5500 x 1.4 = Rs.7700 Increased investment of N = 6500 + 2400 = Rs.8900 Ratio of profit share of M and N = (5500 x 6 + 7700 x 6) : (6500 x 6 + 8900 x 6) = 6:7 So, total annual profit received by them together = 2100 x (13/7) = Rs.3900
