Answer» Correct Answer - Option 1 : 250% Given: A number increases by 25% if 60 is added to it. Formula: Percentage increase = (new - actual)/actual × 100 Calculation: Let the number be x. ⇒ x + 0.25x = x + 60 ⇒ x = 60 × 4 = 240 New number = 240 + 600 = 840 Percentage increase = (840 – 240)/(240) × 100 ⇒ (600/240) × 100 ⇒ 250 ∴ The number should increase by 250%.

Answer» Correct Answer - Option 1 : 250%

Given:

A number increases by 25% if 60 is added to it.

Formula:

Percentage increase = (new - actual)/actual × 100

Calculation:

Let the number be x.

⇒ x + 0.25x = x + 60

⇒ x = 60 × 4 = 240

New number = 240 + 600 = 840

Percentage increase = (840 – 240)/(240) × 100

⇒ (600/240) × 100

⇒ 250

∴ The number should increase by 250%.
