Which two signs should be interchanged to make the given equation correct?
63 - 3 + 45 ÷ 15 × 2 = 36
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. - and ÷.
Given equation: 63 - 3 + 45 ÷ 15 × 2 = 36
After interchanging the signs:
(63 ÷ 3) + 45 - (15 × 2) = 36
⇒ 21 + 45 - 30 = 36
⇒ 66 - 30 = 36
⇒ 36 = 36
