A, B and C started a business in which A contributed Rs 30,000. Out of the total profit of Rs 7200, A got Rs 1920 and C got Rs 2880, find the capital invested by B?

Answer :

TPS
Investment by A = 30,000
total profit = 7200

share of A in profit = 1920
% share of A = (1920/7200)×100 = 26.67 %
share of C in profit = Rs. 2880
share of B in profit = 7200 - 2880 - 1920 = Rs. 2400
% share of B = (2400/7200)×100 = 33.33%

investment by A in the business =  26.67 %
So Rs. 30,000 is 26.67% of total investment in business.
Thus total invested money in business = (30,000/26.67)×100 = Rs. 112500

investment by B = 33.33% of total money
investment by B = (33.33/100)×112500 = Rs. 37,500
Investment by A = 30,000
total profit = 7200 
A'S PROFIT=1920 WHICH IS 26.67%of all profit
B's PROFIT=(7200-1920-2880) 2400 WHICH IS 33.33% of all profit
C'sprofit= 2880 which is 40%of all profit
total capital=112500 (30000/26.66)
b's capital=112500x33.33=37500
cs capital=112500x40=45000
