Which of the mathematical signs should be interchanged in the below equation to make it mathematically correct?
17 + 112 ÷ 16 − 8 × 64 = 175
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. + and ×.
Given equation: 17 + 112 ÷ 16 − 8 × 64 = 175
Option 1: + and ×
After interchanging the expression becomes:
= 17 × 112 ÷ 16 − 8 + 64 = 175
= 17 × 7 − 8 + 64
= 119 − 8 + 64
= 175 = 175
As we have found our answer, there is no need to check further options.
Hence, + and × is the correct answer.
