Question
Ravi and Mohan invested Rs. 32000 and Rs. 20000
respectively in a business. After 6 months, Sohan joined them with an investment of Rs. 36000. At the end of the year, Ravi’s profit share was Rs. 4800 more than Mohan’s. Find the total annual profit earned.Solution
Profit share ratio of Ravi, Mohan and Sohan = (32000 × 12) : (20000 × 12) : (36000 × 6) = 384000 : 240000 : 216000 = 16 : 10 : 9
Let the total profit be Rs. 35x (Sum of 16, 10 and 9)
According to the question,
16x - 10x = 4800
6x = 4800
x = 4800 ÷ 6
x = 800
So, the total profit earned from the business = 35 × 800 = Rs. 28000
