Mother, daughters and apples

We must solve this problem backwards.

When giving the third daughter, the apples are gone. So at that moment the mother only had 1 apple, ie:

half apples (0.5) + half apples (0.5) = 1 apple

Before giving the second daughter:

(1+0,5) * 2 = 3 apples in the basket

Before giving the first daughter:

(3+0,5) * 2 = 7 apples in the basket

Answer: The basket contained 7 apples.
