Answer:

The present age of granddaughter = 6years.

The present age of grandfather = 60years.

Step-by-step explanation:

Given:

• A grandfather is ten times older than his granddaughter.
• He is 54 yrs older than his granddaughter.

Need to find:

• The present age of granddaughter and grandfather.

Explanation:

Let the age of granddaughter = x

Then,the age of grandfather = 10x

As it given that,

Difference between the both ages = 54

Then, According to question

=> 10x - x = 54

=> 9x = 54

=> x = 54/9

=> x = 6

Now

Putting the value of 'x' in the considered ages,

We get:

Age of granddaughter = x

=> 6 years

Age of grandfather = 10x

=> 10×6

=> 60 years

Hence,

The present age of granddaughter is 6years.

The present age of grandfather is 60years.
