Question
A total of Rs. βKβ was to be distributed among A, B,
and C in ratio of 3:4:5 respectively but due to some reason the money was falsely distributed in ratio of 4:3:5 respectively such that B received Rs. 2400 less. Find the value of 2K.Solution
Let the total amount [K] be Rs. 12x
So, amount which B was supposed to receive = 12x Γ (4/12) = Rs. 4x
Amount which was actually received by B = 12x Γ (3/12) = Rs. 3x
ATQ,
4x - 3x = 2400
β x = 2400
Also,
K = 12x = 12 Γ 2400 = Rs. 28800
Therefore, required value,
2K = 2 Γ 28800 = βΉ57600
