Question
The average age of Neha and her uncle at present is 40
years. Neha's age 5 years from now will be one-fourth of the present age of her uncle. What is the current age of her uncle?Solution
ATQ,
Sum of present ages of Neha and her uncle = 40 × 2 = 80 years
Let the present age of Neha = x years
Then, present age of her uncle = (80 - x) years
According to the question,
(x + 5) × 4 = (80 - x)
⇒ 4x + 20 = 80 - x
⇒ 5x = 60
⇒ x = 60 / 5 = 12
So, present age of Neha's uncle = 80 - 12 = 68 years
