Answer 1

Answer:

7 and 35 are the numbers.

Step-by-step explanation:

Let another number be x.

Then positive number = 5x

According to the question, 5x+21=2 (x+21)5x+21=2(x+21)

⇒5x+21=2x+42

⇒5x−2x=42−21

⇒3x=21

⇒x= 21/3 =7

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

Answer 2

Answer:

7 and 35 are the required  positive numbers .

Step-by-step explanation:

Explanation:

Given ,a  positive numbers is 5 times another number.

Let one of the positive number be x  .

Then the other number   be  5x.

On adding 21  in  both the numbers then one of the new number becomes twice the other new number   ,

So,  the numbers  are    x+ 21  and  5x + 21

Step 1:

According to the question  ,

⇒  (5x+ 21 ) = 2 (x+ 21)

⇒ 5x + 21 = 2x + 42  

⇒3x = 42 - 21 = 21

⇒ x = $\frac{21}{3}$ = 7

So ,one of the  number is 7 and the  other is 5x = 5 × 7 = 35

Final answer;

Hence , 7 and 35 are the two positive  numbers .
