Question
'Ankit' and 'Baldev' started a business and invested Rs.
48,000 and Rs. 54,000, respectively. Find the profit share of 'Baldev' out of total profit of Rs. 4,250 at the end of a year.ÂSolution
Ratio of profit shares of 'A' to 'B' = (48,000 x 1) :(54,000 x 1) = 8:9 So, profit share of 'B' = (4,250/17) x 9 = Rs. 2,250
