Which two signs should be interchanged to make the given equation correct?
211 × 14 + 627 ÷ 33 - 17 = 520
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e., × and -.
Given equation: 211 × 14 + 627 ÷ 33 - 17 = 520
Option 4: × and -
⇒ 211 - 14 + (627 ÷ 33) × 17 = 520
⇒ 211 - 14 + (19 × 17) = 520
⇒ (211 + 323) - 14 = 520
⇒ 534 - 14 = 520
⇒ 520 = 520
