Which two signs should be interchanged to make the equation mathematically correct?
112 − 8 + 96 ÷ 16 × 20 = 0
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e.− and +.
Given equation: 112 − 8 + 96 ÷ 16 × 20 = 0
Option 1: − and +
After interchanging the expression becomes:
= 112 + 8 - 96 ÷ 16 × 20 = 0
= 112 + 8 - 6 × 20
= 112 + 8 - 120
= 120 - 120
= 0 = 0
As we have found our answer, there is no need to check further options.
Hence, − and + is the correct answer.
