$\huge \boxed{\pink\star\mathfrak\orange{\large{\underline{\underline{Answer!}}}} }$

Let the number be'x'

Other number= 5x

After adding 21 to both, the numbers are x+21 and 5x+21

Now , according to the question

5x+21= 2(x+21)

⟹5x+21= 2x+42

⟹5x-2x= 42-21

⟹3x= 21

⟹$\boxed{\bold\red{7}}$

$\therefore$

Numbers are 7 and 35

$\huge \boxed{\red\star\mathfrak\purple{\large{\underline{\underline{Verification!}}}} }$

7+21=28

35+21= 56 and 56= 2×28

$\boxed{\bold\green{Hence\: Verified}}$

Answer 2

HEYA!!

let one of the number be x

second number be 5x

2(x+21)=(5x+21)

=> 2x+42=5x+21

=> 2x−5x=21−42

=> −3x=−21

x=7

One of the number 7

Second number 7×5=35
