Question

Rahul's father is thrice as old as Rahul After 12 years he will be just twice his son . find their present ages.

Answer 1

Answer:

present age of rahul = 12

present age of his father = 36

Step-by-step explanation:

let age of rahul be x, age of his father = 3x

After 12 years

     age of rahul = x + 12

     age of his father = 3x + 12

According to question after 12 years rahul's father will be twice the age of his son

Now to make rahul's age = his father's age,

As father's age is twice so it will be equal to his son's age if his son's age also becomes twice

So,

2 ( x + 12 ) = 3x + 12

2x + 24 = 3x + 12

3x - 2x = 24 - 12

x = 12

Answer 2

Answer:

Rahul's father is thrice as old as Rahul (1st statement)

But in the above-mentioned statement we don't Rahul's age, so let's assume Rahul's age is- x

And his father's age is 3x because as the 1st statement says that Rahul's father's age is 3 times of rahul

So, 3x=x

Now,

After 12 years he will be twice as his son (2nd statement)

So, now it is said that after 12 years Rahul's father will be twice as Rahul

So let's assume that 12+(3x)=2x

12+(3x)=2x

12=3x-2x

12=x

x=12

So we found the value of (x) =12

Now, they have asked us to find their present ages so, Rahul's father's present age is

12+(3x)

12+(3)(12)

=48

So Rahul's father's present age is 48 years

Now, let's find Rahul's present age

3(x)

3(12)

36

So Rahul's present age is 36 years
