Answer:
Let the smaller number be x
And another number = 5x
If 21 is added to both the numbers then as per the given condition;
5x+21 = 2×(x+21)
5x + 21 = 2x + 42
5x – 2x = 42 – 21
3x =. 21
x = 21/3= 7
Therefore, the positive number is = 5×7 = 35
Hence, Original numbers are 7 and 35.

Answer:
let the first number be x
other number = 5x
then after 21 adding to both
first number = x+21
other number= 5x+21
according to the question
(x+21)2= 5x+21
2x+42=5x+21
42-21=5x-2x
21=3x
21/3=x
x =7
so the numbers are
first number =7
other number =5x= 5×7=35
