LET. AGE OF MAYUR = X

BEFORE 8 YEAR HER. AGE WAS = (X-8) YEAR

after 5 year =( x+5)

$= > > >$


(x+5)=2(x-8)

x+5=2x-16

x=21. year

Answer 2

Answer:

Mayur is 21 years old.

Step-by-step explanation:

Given :

After 5 years = Mayur will be twice the age he was 8 years ago

To find :

His present age

Solution :

Let his present age be y

Age after 5 years after = y + 5

Age 8 years back = y - 8

⇒ 2(y - 8) = y + 5

⇒ 2y - 16 = y + 5

⇒ 2y - y = 5 + 16

⇒ y = 21

Mayur's present age = 21 years old.

Therefore, Mayur is 21 years old.

$\rule{300}{1.5}$

Verification :

Mayur's age after 5 years =

⇒ 21 + 5

⇒ 26

Mayur's age 8 year ago =

⇒ 21 - 8

⇒ 13

Check if his age 8 years back is half of his age after 5 years,

⇒ 13 × 2

⇒ 26

Therefore, Mayur is 21 years old.
