Which two signs should be interchanged in the following equation to make it correct?
525 ÷ 15 - 3 × 5 + 200 = 300
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. × and -
Given equation: 525 ÷ 15 - 3 × 5 + 200 = 300
From option 1, by interchanging signs × and -, we get
(525 ÷ 15) × 3 - 5 + 200
= (35 × 3) - 5 + 200
= 105 - 5 + 200
= 305 - 5
= 300
Hence, option 1 is correct.
