You can put this solution on YOUR website! In these type of questions the birth year is not known. Therefore, we will have to check all answers.
-----------
Checking of Answers:
Let the birth year be x.
Let y = (1/90 * x) = chetan's age in 2002
Therefore, x = 90 * y = birth year
If y = 30 then x = 2700 > 2002. Therefore, this option is not possible.
If y = 28 then x = 2520 > 2002. Therefore, this option is not possible.
If y = 26 then x = 2340 > 2002. Therefore, this option is not possible.
If y = 22 then x = 1980 < 2002. Therefore, this option is possible.
Therefore, chetan is 22 years old in 2002.
-----------
Question:
what is his age in 2006?
As chetan is 22 years old in 2002, therefore his age in 2006 will be 22 + 4 = 26 because the difference b/w 2002 and 2006 is 4.
-----------
Ans:
Chetan is 26 years old in 2006
-----------
Summary:
You just have to check the possibility of answers using the above mentioned method. And then just add the value of difference in the value of possible answer.
