Which two signs should be interchanged to make the equation mathematically correct?
124 - 8 + 96 ÷ 16 × 20 = 12
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. - and +
Given equation: 124 - 8 + 96 ÷ 16 × 20 = 12
Option 2: - and +
After interchanging the expression becomes:
⇒ 124 + 8 - (96 ÷ 16) × 20 = 12
⇒124 + 8 - (6 × 20) = 12
⇒124 + 8 - 120 = 12
⇒132 - 120 = 12
⇒12 = 12
Hence, the correct answer is - and +.
