Question

Twenty percent of a number when added to 20 becomes the number itself. Find the number

Answer 1

Answer:25

Step-by-step explanation:

20% of a number means 20/100=1/5th of the number

Let m be the number

m/5 + 20 = m

(m+100)/5=m

m+100=5m

4m=100

m=25

Answer 2

The number is 25

Step-by-step explanation:

Let the number be x

Twenty percent of a number when added to 20 becomes the number itself.

So, $20\% x+20=x$

$\frac{20}{100}x+20=x$

$20=x-\frac{20}{100}x$

$20=\frac{80}{100}x$

$\frac{2000}{80}=x$

25 = x

Hence The number is 25
