Which two numbers should be interchanged to make the given equation correct?
68 + 85 - 15 ÷ 5 × 3 = 32
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1, i.e., 85 and 15.
Given equation: 68 + 85 - 15 ÷ 5 × 3 = 32
After interchanging the numbers:
68 + 15 - (85 ÷ 5) × 3 = 32
⇒ 68 + 15 - (17 × 3) = 32
⇒ (68 + 15) - 51 = 32
⇒ 83 - 51 = 32
⇒ 32 = 32
