Question
The average of present ages of
Rajesh and his father is 45 years. The age of Rajesh 5 years hence from now will be 1/4 of the present age of his father. Find the present age of Rajesh's father.Solution
ATQ, Sum of present ages of Rajesh and his father = 45×2 = 90 years Let the present age of Rajesh be 'x' years. Then, present age of Rajesh's father = 90−x years. According to the question, (x+5)×4 = (90−x) 4x+20 = 90−x 5x = 70 x = 70/5 = 14 So, present age of Rajesh's father = 90−14 = 76 years.
