Answer:

10

Explanation:

1 child likes all three

4 like apples and bananas, so 4-1 = 3 like apples and bananas only

3 like apples and peaches, so 3-1 = 2 like apples and peaches only

2 like peaches and bananas, so 2-1 = 1 like peaches and bananas only

7 like apples, but 3+2+1 like one or more other fruits, so 1 likes apples only

6 like bananas, but 3+1+1 like one or more other fruits, so 1 likes bananas only

5 like peaches, but 2+1+1 like one or more other fruits, so 1 likes peaches only

__

1 + 1 + 1 = 3 like exactly 1 fruit;

3 + 2 + 1 = 6 like exactly 2 fruits;

1 likes exactly 3 fruits.

The total number of children is 3 + 6 + 1 = 10.

Assuming all the referenced children are in the family, there are 10 children in the family.
