Understanding the Problem
We need to determine the present age of Lakhan based on the information given about both friends' ages.
Given Information
- The sum of their ages 14 years ago was one-third of the sum of their present ages.
- Avish's present age is four-thirds of Lakhan's present age.
Let’s Define Variables
- Let Lakhan's present age be L years.
- Consequently, Avish's present age will be (4/3)L years.
Setting Up the Equation
1. Current Ages:
- Sum of present ages = L + (4/3)L = (7/3)L.
2. Ages 14 Years Ago:
- Lakhan's age 14 years ago = L - 14.
- Avish's age 14 years ago = (4/3)L - 14.
- Sum of ages 14 years ago = (L - 14) + ((4/3)L - 14) = (7/3)L - 28.
3. Formulating the Equation:
- According to the problem, (7/3)L - 28 = (1/3)((7/3)L).
- Simplifying this gives us: (7/3)L - 28 = (7/9)L.
Solving the Equation
- Rearranging the equation leads to:
- (7/3)L - (7/9)L = 28.
- Converting (7/3)L to a common denominator:
- (21/9)L - (7/9)L = 28
- (14/9)L = 28.
- Multiplying both sides by 9/14:
- L = 18.
Conclusion
Thus, the present age of Lakhan is 18 years.
