Which two numbers should be interchanged to make the equation correct?
10 - 26 + 12 × 20 ÷ 5 = 18
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 10 and 20.
10 - 26 + 12 × 20 ÷ 5 = 18
After interchanging numbers,
⇒ 20 - 26 + 12 × (10 ÷ 5) = 18
⇒ 20 - 26 + (12 × 2) = 18
⇒ 20 - 26 + 24 = 18
⇒ 44 - 26 = 18
⇒ 18 = 18
Hence, the correct answer is 10 and 20.
