(e)12
Answer
Answer (as printed): A
Explanation
Let the age of Rahul, Sagar and Purav be x, y and z respectively According to the given information Age of Sagar – Age of Rahul = Age of Rahul – Age of Purav ⇒y–x=x–z ⇒ 2x = y + z …(i) Also y + z = 66 years From (i) x = 33 years Also as per Eq (i) we have Purav’s age + Sagar’s age = 66 years. By going through option (a) given Purav = 18, and Rahul = 33 years, Sagar = 48 years Difference between Rahul’s and Purav’s age = 18 years
