1. Answer:

   7 , 35 is the correct answer

   Step-by-step explanation:

   Given that a positive number is 5 times the another number.

   Let one number be x.

   and the other number is 5x.

   Now, 21 is added to both the numbers and one of the new number becomes twice the other new number.

   ∴2 ( x + 21 ) = 5x + 21

   42 + 2x = 5x + 21

   3x = 21

   ∴x = 7

   So the other no. is 5x = 5 × 7 = 35

   So, one number is 7 and the other number is 35.

2. Step-by-step explanation:

   Let another number be x.

   Then positive number = 5x

   According to the question,

   5x+21 = 2(x+21)

   5x+21=2x+42

   5x-2x=42-21

   5x−2x=42−21

   3x=21

   x=21/3

   x= 7

   Hence another number = 7 and positive number = 7 x 5 = 35.
