Question
M and N started a business by investing Rs.6000 and
Rs.7800 respectively. After 6 months, M and N increased their investments by 40% and Rs.2400 respectively. The annual profit share of N was Rs.2000. Find the total annual profit received by them together.Solution
Increased investment of M = 6000 x 1.4 = Rs.8400 Increased investment of N = 7800 + 2400 = Rs.10200 Ratio of profit share of M and N = (6000 x 6 + 8400 x 6) : (7800 x 6 + 10200 x 6) = 4:5 So, total annual profit received by them together = 2000 x (9/5) = Rs.3600
