Which two signs should be interchanged to make the equation mathematically correct?
42 + 14 ÷ 28 × 98 - 14 = 105
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. + and ×.
Given equation: 42 + 14 ÷ 28 × 98 - 14 = 105
Option 1: + and ×
After interchanging the expression becomes:
= 42 × 14 ÷ 28 + 98 - 14 = 105
= 21 + 98 - 14
= 119 - 14
= 105 is equal to 105.
As we have found our answer, there is no need to check further options.
Hence, + and × is the correct answer.
