Which two signs need to be interchanged to make the following equation correct?
9 + 6 × 3 - 9 ÷ 1 = 10
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. ÷ and -
9 + 6 × 3 - 9 ÷ 1 = 10
After interchanging signs,
⇒ 9 + 6 × (3 ÷ 9) - 1 = 10
⇒ 9 + (6 × 1/3) - 1 = 10
⇒ 9 + 2 - 1 = 10
⇒ 11 - 1 = 10
⇒ 10 = 10
