mother, her daughter and her grand child weighs 140 kg. daughter and her daughter ( child ) weighs 60 kg. child is 1 / 5 th of her grand mother. what is the age of the daughter?
subtract(60, divide(subtract(140, 60), 5))
"mother + daughter + child = 140 kg daughter + child = 60 kg mother = 140 - 60 = 80 kg child = 1 / 5 th of mother = ( 1 / 5 ) * 80 = 16 kg so now daughter = 140 - ( mother + child ) = 140 - ( 80 + 16 ) = 44 kg answer : a"
