Question
M and N started a business by investing Rs.5000 and
Rs.6000 respectively. After 7 months, M and N increased their investments by 60% and Rs.2100 respectively. The annual profit share of N was Rs.2200. Find the total annual profit received by them together.Solution
Increased investment of M = 5000 x 1.6 = Rs.8000 Increased investment of N = 6000 + 2100 = Rs.8100 Ratio of profit share of M and N = (5000 x 7 + 8000 x 5) : (6000 x 7 + 8100 x 5) = 10:11 So, total annual profit received by them together = 2200 x (21/11) = Rs.4200
