Question

At a supermarket sale, 2 more than half of the number of apples were taken out from a box. Later, 2 fewer than half of the remaining number of apples were taken out again. If 20 apples were left in the box, how many apples were there at first?

Answer 1

x/2 + 2 taken, leaving x/2 - 2
(x/2 - 2)/2 - 2 taken, leaving x/4 + 1
so, x/4 + 1 = 20
x = 76

check:
76 - 40 = 36
36 - 16 = 20

Answer 2

20
