Question

Ahmed's father is thrice as old as ahmed . after 12 years ,his age will be twice that of his son. Find their present age

Answer 1

Let Ahmed's age be x
Father's age = 3x
After 12 years father's age = 2(x+12)
So 3x+12 = 2(x+12)
3x+12== 2x+24
3x-2x = 24-12
x = 12
Ahmed's age is 12
Father's age = 3x =3(12) = 36

Answer 2

Answer:

The present age of Ahmed and Ahmed's father is 12 and 36 respectively.

Step-by-step explanation:

Given : Ahmed's father is thrice as old as Ahmed. After 12 years, his age will be twice that of his son.

To Find : Their present age ?

Solution :

Let the Ahmed's age be 'x'.

Ahmed's father is thrice as old as Ahmed.

i.e. Ahmed's father age is '3x'

After 12 years, his age will be twice that of his son.

i.e. $3x+12 = 2(x+12)$

Solving the equation,

$3x+12 = 2x+24$

$x=12$

So, Ahmed's age is 12.

Ahmed's father age is $3\times 12=36$

Therefore, The present age of Ahmed and Ahmed's father is 12 and 36 respectively.
