Question
The ratio between the present age of Beena and Meenal is
5:7, where Sumit is 6 years younger than Meenal then find the ratio of their ages 9 years hence.Solution
Let present age of Beena be 5x years and of Meenal of 7x years. According to the question, => 5x = 7x – 6 => x = 3 Present age of Beena = 5 × 3 = 15 years Present age of Meenal = 7 × 3 = 21 years Now, 9 years hence their ratio of ages, Beena age = 15 + 9 = 24 years Meenal age = 21 + 9 = 30 years Required ratio = 24:30 = 4:5
