Question

A brother and sister share out their collection of 5000 stamps in the

ratio 5:3. The brother then shares his stamps with two friends in
the ratio 3:1:1, keeping most for himself. How many stamps do
each of his friends receive?
13​

Answer 1

1875

Explanation:

After sharing in the ratio 5:3, the brother has

5000/(5+3) x 5 = 3125

Next, he shares with his friend in the ratio 3:1:1, thus

3125/(3+1+1) x 3 = 1875
