Which two signs should be interchanged to make the given equation correct?
10 = 3 ÷ 2 - 5 + 1 × 11
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. × and =.
Given : 10 = 3 ÷ 2 - 5 + 1 × 11
According to the question, after replacing the signs :
Option 1) × and =
10 = 3 ÷ 2 - 5 + 1 × 11
⇒ 10 × (3 ÷ 2) - 5 + 1 = 11
⇒ (10 × 1.5) - 5 + 1 = 11
⇒ (15 + 1) - 5 = 11
⇒ 16 - 5 = 11
⇒ 11 = 11
