Which two signs should be interchanged to make the given equation correct?
312 – 13 × 14 + (207 ÷ 4) = 539
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. ÷ and –.
After interchanging the signs we get;
312 ÷ 13 × 14 + 207 - 4 = 539
⇒ (24 × 14) + 207 - 4 = 539
⇒ 336 + 207 - 4 = 539
⇒ 543 - 4 = 539
⇒ 539 = 539
