Which two digits and signs need to be interchanged so as to balance the given equation?
97 ÷ 24 − 16 × 5 + 37 = 53
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1. i.e. 7 and 6; + and −.
Given equation: 97 ÷ 24 − 16 × 5 + 37 = 53
Option 1: 7 and 6; + and −
After interchanging the expression becomes:
= 96 ÷ 24 + 17 × 5 - 36 = 53
= 4 + 17 × 5 - 36
= 4 + 85 - 36
= 89 - 36
= 53 is equal to 53.
As we have found our answer, so, there is no need of checking other options.
Hence, option 1 is the correct answer.
