Question

a man gave 5 / 12 of his money to his son. 3/7 of the remainder to his daughter and the remaining to his wife .if his wife gets 87 rupees what was the total amount.

Answer 1

gave 5/12 to son

remaining = 1 - 5/12 = 7/12

gave 3/7 to his daughter

remaining = 1 - 3/7 = 4/7

his wife is left with 87 rupees

let the total amount be x

so, 4/7 of 7/12 of x = 87

4/7 * 7/12 * x = 87

x = (87*12*7) / 7*4

x = 261

total amount was 261
