Question
‘X’ and ‘Y’ started a business together. The
amount invested by ‘X’ is 40% more than that of ‘Y’, while ‘Y’ invested his amount for 20% less time than ‘X’. What is the ratio of the profits earned by ‘X’ and ‘Y’ after a year?Solution
ATQ,
Let the amount invested by ‘Y’ be Rs. a
Therefore, amount invested by ‘X’ = Rs. 1.4a
Let the time for which ‘X’ invested be ‘b’ months
Therefore, time for which ‘Y’ invested = 0.8b months
Ratio of the profits earned = (1.4a × b):(a × 0.8b) = (1.4b):(0.8b) = 14:8 = 7:4
