Question
M and N started a business by investing Rs.4200 and
Rs.6000 respectively. After 6 months, M and N increased their investments by 40% and Rs.2400 respectively. The annual profit share of N was Rs.1800. Find the total annual profit received by them together.Solution
Increased investment of M = 4200 x 1.4 = Rs.5880 Increased investment of N = 6000 + 2400 = Rs.8400 Ratio of profit share of M and N = (4200 x 6 + 5880 x 6) : (6000 x 6 + 8400 x 6) = 7:10 So, total annual profit received by them together = 1800 x (17/10) = Rs.3060
