Which of the mathematical signs should be interchanged in the below equation to make it mathematically correct?
105 ÷ 15 × 54 + 6 − 18 = 222
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. ÷ and +.
Given equation: 105 ÷ 15 × 54 + 6 − 18 = 222
Option 1: ÷ and +
After interchanging the expression becomes:
= 105 + 15 × 54 ÷ 6 − 18 = 222
= 105 + 15 × 9 − 18
= 105 + 135 − 18
= 240 - 18
= 222 = 222
As we have found our answer, there is no need to check further options.
Hence, ÷ and + is the correct answer.
