At present, the ratio between the ages of Arun and Deepak is 3 : 2. After 13 years, Arun's age will be 34 years. What would be the age of Deepak after 8 years from now ?
OPtion
1) 14 Years
2) 15 Years
3) 17 Years
4) 18 Years
5) 19 Years
6) 20 Years
7) 21 Years
8) 22 Years
9) 23 Years
10) None of these
Solution
Let the present ages of Arun and Deepak be 3x years and 2x years respectively. Then,
3x + 13 = 34 => 3x = 21
x = 7
Deepak's present age = 2x = 14 years.
Deepak's Age after 8 years = 14 + 8 = 22 Years
