What is to be added to 15% of 180 so that the sum is equal to 20% of 360?1. 602. 503. 454. 40

Answer» Correct Answer - Option 3 : 45

Calculations:

Let the number added be x.

15% of 180 + x = 20% of 360

⇒ 180 × (15/100) + x = 360 × (20/100)

⇒ 27 + x = 72

⇒ x = 72 - 27 = 45

∴ The number to be added is 45.
