5. If a number multiplied by 20% of itself gives
a number which is 100% more than the
number, then the number is ......​

Answer 1

Answer:

10

Step-by-step explanation:

Let the number be x

Then 20% of the number will be 20/100 × x

= x/5

According to the question,

x × x/5 = x + x × 100/100

x²/5 = 2x

x² = 10x

x = 10
