A man left one-third of his property to his daughter, one-fourth to his son, and the remaining Rs. 20000 to his wife. How much money did the man leave?
let the man's property be x
the daughter's property = 1/3x
the son's property = 1/4x
x - (1/3x + 1/4x ) = 20,000
x - (4/12x + 3/12x ) = 20,000
x - 7/12x = 20,000
12/12x - 7/12x = 20,000
5x/12 = 20,000
5x = 20,000 x 12
5x = 24,000
x = 240000/5
x = 48000
so the man's property = 48000 rs
