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