Question 91
The difference between the present ages of Anil and Sudhir is 6 years. The ratio between their ages after 4 years will be 3:4. What can be the present age of Sudhir ?
Solution
Let the age of Anil and Sudhir be x and y respectively.
Now, y-x = 6
(x+4)/(y+4) = 3/4
4x - 3y = -4
Therefore, on solving we get,
x = 14 and y = 20
Hence, Sudhir's age is 20 years.
