Question

He subtracted 5 from 12, which equals 7 and then added 7 to 10. But the answer should be?

1) 7
2) 10
3) 12
4) 15

Answer 1

The correct calculation involves subtracting 5 from 12 to get 7, and then adding this result to 10 to get 17. The correct answer, 17, is not listed among the choices provided in the question.

The question involves performing two operations: subtraction and addition. Initially, you subtract 5 from 12, which gives you 7, as the subtraction of two positive numbers is straightforward.

Then you add this result to 10, which also involves only positive numbers.

First, let's follow the subtraction rule: 12 - 5 equals 7. Then, apply the addition rule for two positive numbers: Adding the result to 10 gives 10 + 7, which equals 17.

Therefore, the correct answer is not among the options provided; it is 17.
