Given:

✰ 20% of a number is 8

To find:

✠ The number

How to solve?

❀ 20% of number means 20% × the number. As we supposed that number 'x' , So it will be 20% × x. Here 20% is in percentage amount and x is original number. Now, to remove that percentage sign we will divide it by 100. So we have 20/100 × x and we know it is equal to 8. So we will get equation and can easily find it's value.

Solution:

Let the number be x.

According to the question,

➲ 20/100 × x = 8

➲ 2/10 × x = 8

➲ 1/5 × x = 8

Multiply 5 by 8 ( cross multiplication )

➲ x = 8 × 5

➲ x = 40

∴ The number = 40
