Which two numbers (not the digits of the numbers) and two signs should be interchanged to make the given equation correct?
10 ÷ 2 × 6 - 15 + 5 = 25
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 5 and 2; + and -
Given equation: 10 ÷ 2 × 6 - 15 + 5 = 25
After interchanging signs and numbers:
(10 ÷ 5) × 6 + 15 - 2 = 25
⇒ (2 × 6) + 15 - 2 = 25
⇒ (12 + 15) - 2 = 25
⇒ 27 - 2 = 25
⇒ 25 = 25
