Question
At a family event, the present ages of Mira and Junaid
are in the ratio of 2:5. Moreover, Imran is 7 years younger than Mira. Twelve years ago, Imran's age was half of Mira's age at that time. Determine Junaid's current age.Solution
ATQ;
Mira:Junaid = 2:5 → Mira = 2k, Junaid = 5k Imran = Mira − 7 = 2k − 7 12 years ago: Imran = 2k − 19, Mira = 2k − 12 Condition: 2k − 19 = ½(2k − 12) → 2k − 19 = k − 6 → k = 13 So: Mira = 26 Junaid = 65 Imran = 19 Hence, Junaid’s current age = 65
