Which of the mathematical signs should be interchanged in the below equation to make it mathematically correct?
72 - 12 + 8 × 6 ÷ 24 = 30
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. - and ÷.
Given equation: 72 - 12 + 8 × 6 ÷ 24 = 30
Option 1: - and ÷
After interchanging the expression becomes:
= 72 ÷ 12 + 8 × 6 - 24 = 30
= 6 + 8 × 6 - 24
= 6 + 48 - 24
= 54 - 24
= 30 is equal to 30.
Hence, - and ÷ is the correct answer.
