Which two signs should be interchanged to make the given equation correct?
3 × 12 - 6 ÷ 2 + 12 = 16
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. - and ÷.
Given equation: 3 × 12 - 6 ÷ 2 + 12 = 16
After interchanging the expression becomes:
= 3 × (12 ÷ 6) - 2 + 12 = 16
⇒ (3 × 2) - 2 + 12 = 16
⇒ 6 - 2 + 12 = 16
⇒ 18 - 2 = 16
⇒ 16 = 16
