Which two signs should be interchanged in the following equation to make it correct?
87 × 24 ÷ 12 – 16 + 14 = 176
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. − and +.
Given equation: 87 × 24 ÷ 12 – 16 + 14 = 176
Option 1: - and +
After interchanging the expression becomes:
= 87 × 24 ÷ 12 + 16 - 14 = 176
= 87 × 2 + 16 - 14
= 174 + 16 - 14
= 176 = 176
As we have found our answer, there is no need to check further options.
Hence, - and + is the correct answer.
