      Rhea is 4 years elder to Mohan. The ratio of Rhea’s

      age 6 years ago to Mohan’s age 2 years hence is 3:4. What is Mohan’s present age?
      A 14 yrs Correct Answer Incorrect Answer
      B 22 yrs Correct Answer Incorrect Answer
      C 26 yrs Correct Answer Incorrect Answer
      D 28 yrs Correct Answer Incorrect Answer

      Solution

      ATQ,

      Let Rhea’s present age = x

      Then Mohan’s present age = x – 4

      (x – 6) / ((x – 4) + 2) = 3 / 4

      ⇒ (x – 6) / (x – 2) = 3 / 4

      ⇒ 4x – 24 = 3x – 6

      ⇒ x = 18

      Mohan’s age = x – 4 = 18 – 4 = 14 years
