The difference of two numbers is 20% of the larger number. If the smaller number is 20, the larger number is :

1. 25
2. 45
3. 50
4. 80

Correct Option: A

Let the larger number be y.
⇒ According to question,
y – 20 = 20% of y

or, y – 20 =	y
	5

or, y –	y	= 20
	5

or, 5y – y = 20 × 5
or, 4y = 20 × 5
⇒ y = 5 × 5 = 25
