Question 30

In 2004, Rohini was thrice as old as her brother Arvind. In 2014, Rohini was only six years older than her brother. In which year was Rohini born?

Solution

In 2004, let age of Arvind be x, then age of Rohini will be 3x.

It is also given that in 2014, she is older by 6 years than her brother.

It means that their ages differ by 6 years.

So, 3x - x = 6

2x = 6

x=3.

In 2004, Arvind age is 3 years and Rohini age is 9 years.

Hence, Rohini was born in 1995.
