Question

The diference of two numbers is 20% of the larger number, if the smaller number is 20, then the larger number is :

A) 15 B) 25 C) 35 D) 45

Answer 1

Answer:

25 pls mark as brilliant

Step-by-step explanation:

Let x be the larger number and y be the smaller number

Therefore x-y=20%of x

Now put the value of smaller number in the equation

x-20=(20÷100)×x

x-20=(1/5)×x

Here 5 is in denominator.

As we bring 5 on the left side of equation it will be multiplied by x-20

Now the equation will be 5 ×(x-20)=x

5x-100=x

Bring 100 on right side of = and x on the left side of =

So it will become 5x-x=100

4x=100

x=100÷4

x=25

Therefore the larger number is 25.
