Answer:
7
Step-by-step explanation:
If John had 10 apples and found four more, he would have 14 apples. If he lost half of all of his apples he would have 7 left.
However, if he lost only half of the four he found, then he would have 10 + 2 or 12.
If the four he found were part of the 10 apples he had , and he lost half of all his apples he would have 5 left. However, if he only lost half of the four apples that he found (and which were part of the original ten apples), then he would 8 apples left.
I suppose the most obvious answer is the first - (10+4)/2, which equals 7.
