Rs.5600 respectively. After 5 months, M and N increased their investments by 40% and Rs.1500 respectively. The annual profit share of N was Rs.2100. Find the total annual profit received by them together.Solution
Increased investment of M = 4500 x 1.4 = Rs.6300 Increased investment of N = 5600 + 1500 = Rs.7100 Ratio of profit share of M and N = (4500 x 5 + 6300 x 7) : (5600 x 5 + 7100 x 7) = 6:7 So, total annual profit received by them together = 2100 x (13/7) = Rs.3900
