Question

que.
After 32 years, Rahim will be 5 times as old as he was 8 years ago. How old is Rahim today?​

Answer 1

Answer:

Let Rahim age=x

By statement

x+32=5(x−8)

x+32=5x−40

72=4x

x=18

Rahim is 18 years old today.

Answer 2

Answer:

We have given that,

After 32 years, Rahim will be 5 times as old as he was 8 years ago.

Let the present age of Rahim be ‘x’ years.

8 years ago;

Rahim’s age 8 years ago would be = (x – 8) years

Now,

After 32 years from the present age;

Rahim’s age after 32 years will be = (x + 32) years------- (1)

According to the question,

After 32 years, Rahim will be 5 times as old as he was 8 years ago.

Converting into numerical form;

After 32 years,

Rahim’s age will be = 5(x−8)

------ (2)

On equating equation (1) and equation (2), we obtained

⇒x+32=5(x−8)

Now, solving for the value of ‘x’.

Simplifying the above equation, we get

⇒x+32=5x−40

Subtracting 32 from both the sides of the equation, we get

⇒x=5x−72

Subtracting 5x from both the sides of the equation, we get

⇒−4x=−72

Dividing both the sides of the equation by -4, we get

⇒x=18

Therefore,

The present age of Rahim is ‘x’ which is equal to 18 years.

Rahim’s today age is 18 years.

Hence, it is the required answer.
