The ratio of the present ages of Monu and Sony is 3 : 4. The ratio of the age of Monu 5 years ago and that of Sonu 5 years hence is 2 : 5. Find Monu‘s present age.
Given:
Ratio of Monu's and Sonu's present ages = 3:4
Ratio of Monu’s age 5 year ago to Sonu’s age 5 years hence = 2:5
Solution:
Let Monu’s present age = 3x, Sonu’s present age = 4x
From the condition:
5(3x - 5) = 2(4x + 5)
15x - 25 = 8x + 10
Thus, Monu's age = 3 = 15 years
