Question
In 6 years, Divya's age will be 40% less than Malu's age
at that time, and currently, Divya's age is 25% more than Soni's age. Additionally, the age of Malu when Divya was born is equal to Soni's current age. Find the present age of Malu.Solution
Ratio of the ages of Divya and Malu after 6 years = 60:100 = 3:5 Ratio of the ages of Divya and Soni = 125:100 = 5:4 (m + 6)/(d + 6)=5/3 3m + 18=5d + 30 3m – 5d=12 s/d=4/5 d=5s/4 m – d=s m – 5s/4=s 4m – 5s=4s 4m=9s 4m/9=s d =5(4m/9)/4=5m/9 3m – 5d=12 3m-5 * (5m/9)=12 27m – 25m=12 * 9 m =54 years
