Answer 2

Answer: The correct number of "16% of a number is added to 21,

then it gets itself" is 25.

Step-by-step explanation:

Let the number be 'x'.

16 % of number x

⇒ 16x/ 100 = 4x/ 25

According to question,

16% of a number is added to 21, then it gets itself

we know that 16% of x is 4x/25. so if we will add 4x/25 and 21 then the result will be the number itself i.e. x.

⇒ 4x/25 + 21 = x

⇒ x - 4x/25 = 21

⇒21x/25 = 21

⇒ 21x= 21 x 25

⇒ x = 25.

Hence, the number is 25.
