**Rahim's age is 2/9 of his grandfather's. His grandfather will be 100 years old in 19 years' time. In how many years' time will Rahim's age be 1/4 of his grandfather?Solution**

Now

Rahim --> 2 units

Grandfather --> 9 units

19 years' time (Grandfather)

9 units + 19 --> 100

9 units --> 100 - 19 = 81

1 unit --> 81 divided by 9 = 9

Now

Rahim --> 2 x 9 years = 18 years

Grandfather --> 9 x 9 years = 81 years

Difference between Grandfather and Rahim

--> 81 years - 18 years = 63 years

Future (when Rahim 1/4 of Grandfather's age)

Rahim --> 1 unit

Grandfahter --> 4 units

But Rahim is 63 years younger

4 units - 1 unit --> 63 years

3 units --> 63 years

1 unit --> 63 years divided by 3 = 21 years

Rahim now --> 18 years

Rahim in future --> 21 years

21 years - 18 years = 3 years

**Answer: 3 years**
