Which two signs should be interchanged to make the given equation correct?
28 + 12 - 6 × 40 ÷ 8 = 46
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. + and -
Given equation: 28 + 12 - 6 × 40 ÷ 8 = 46
Option 1: + and -
After interchanging the expression becomes:
= 28 - 12 + 6 × 40 ÷ 8 = 46
= 28 - 12 + 6 × 5
= 28 - 12 + 30
= 58 - 12
= 46 = 46
Hence, + and - is the correct answer.
