Which two signs should be interchanged to make the equation mathematically correct?
96 × 8 + 27 ÷ 6 - 12 = 162
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. × and ÷.
Given equation: 96 × 8 + 27 ÷ 6 - 12 = 162
Option 1: + and -
After interchanging the expression becomes:
= 96 × 8 - 27 ÷ 6 + 12 = 162
= 775.5 is not equal to 162.
Option 2: × and ÷
After interchanging the expression becomes:
= 96 ÷ 8 + 27 × 6 - 12 = 162
= 12 + 27 × 6 - 12
= 12 + 162 - 12
= 162 is equal to 162.
As we have found our answer, there is no need to check further options.
Hence, × and ÷ is the correct answer.
