Which two numbers and two signs should be interchanged in the following equation to make it correct?
3 - 17 + 3 + 16 × 8 = 60
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 17 and 16, - and ×.
Given equation: 3 - 17 + 3 + 16 × 8 = 60
Option 1: 17 and 16, - and ×
After interchanging the expression becomes:
= 3 × 16 + 3 + 17 - 8 = 60
= 48 + 3 + 17 - 8
= 68 - 8
= 60 = 60
Hence, 17 and 16,- and × is the correct answer.
