Answer 2

Hii....
Here is your answer
___________________________________________________

Let, the number be x
Then, another number be 5x

A. T. Q

Adding 21 in both the number sides

Then,
One number = 2 × another number

5x + 21 = 2( x + 21 )

5x + 21 = 2x + 42

5x - 2x = 42 - 21

-3x = -21

x = 21/3

x = 7

Hence, the another number is 7

Therefore, positive number is 5x
= 5 × 7
= 35
