M and N started a business by investing Rs.6000 and
Rs.7000 respectively. After 6 months, M and N increased their investments by 40% and Rs.2800 respectively. The annual profit share of N was Rs.2100. Find the total annual profit received by them together.Solution
Increased investment of M = 6000 x 1.4 = Rs.8400 Increased investment of N = 7000 + 2800 = Rs.9800 Ratio of profit share of M and N = (6000 x 6 + 8400 x 6) : (7000 x 6 + 9800 x 6) = 6:7 So, total annual profit received by them together = 2100 x (13/17) = Rs.3900
