Which two signs should be interchanged to make the given mathematical equation correct?
24 ÷ 4 - 18 + 2 × 5 = 14
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. + and -.
Given equation: 24 ÷ 4 - 18 + 2 × 5 = 14
After interchanging the signs:
(24 ÷ 4) + 18 - (2 × 5) = 14
⇒ 6 + 18 - 10 = 14
⇒ 24 - 10 = 14
⇒ 14 = 14
