Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. 22.22%.

Two successive percentage decreases of 25% each = 25 + 25 - (25 × 25)/100 = 25 + 25 - 6.25 = 43.75%

Two successive percentage increase of 25% each = 25 + 25 + (25 × 25)/100 = 25 + 25 + 6.25 = 56.25%

Difference = 56.25% - 43.75% = 12.5%

Required percentage = (12.5/56.25) × 100 = 22.22...% = 22.22% (approx)

Therefore, the required percentage is 22.22%.
