Question

Mary spent 1/4 of her money on juice and 4/15 of the remainder on food.What fraction of the money did she save?

Answer 1

Answer:

Sol : Let us assume Mary had money = 1

       So spent 1/4 of her money, left with = 1-1/4 = 3/4

       then she spent 4/15 of the remainder on food = 3/4 *4/15 = 1/5

   ∴ Her savings = 3/4-1/5 = 11/20
