Question

Ramanath is 7 times as old as his son after 8 years he will be three times as old as his son at that time find their present ages

Answer 1

Given that:

• Ramanath is 7 times as old as his son.
• After 8 years he will be three times as old as his son.

To Find:

• Their present ages.

Let us assume:

• Present age of Ramanath's son be x.
• Then, Ramanath's age = 7x

After 8 years:

• Ramanath's age = 7x + 8
• His son's age = x + 8

According to the question:

»»» 7x + 8 = 3(x + 8)

»»» 7x + 8 = 3x + 24

»»» 7x - 3x = 24 - 8

»»» 4x = 16

»»» x = 16/4

»»» x = 4

Hence,

• Ramanath's present age = 7x = 7(4) = 28 years
• His son's age = x = 4 years

Answer 2

GIVEN :-

• Ramanath is 7 times as old as his Son after and year he will be 3 times as old his son

TO FIND :-

• their present age = ?

SOLUTION :-

let present age of his son is 'x

Ramanath is 7 time as old as his son

Ramanath age is 7x

7x+8 = (x+8) x 3 after 8 years

7x+ 8 = 3x + 24

4x= 16 ⇒ x = 4

present age of his son is 4 year

Ramanath age is 28 years

Ramanath present age is 28 year his son present age is 4 year
