Which two numbers should be interchanged to make the given equation correct?
9 + 4 ÷ 2 – 6 × 3 = 4 ÷ 3 × 6 – 9 + 1
Answer & explanation
Correct answer: option 3
9 + 4 ÷ 2 – 6 × 3 = 4 ÷ 3 × 6 – 9 × 1
⇒ 9 + 6 ÷ 2 – 4 × 3 = 6 ÷ 3 × 4 – 9 × 1
⇒ 9 + 3 – 4 × 3 = 2 × 4 – 9 + 1
⇒ 12 – 12 = 8 – 9 + 1
0 = 0
L.H.S. = R.H.S.
So, option (C) is correct answer.
