Question
Five years from now, K and M together will be 80 years
old. If their present ages are in the ratio 4:3, find the difference in their ages.Solution
Let the present ages of K and M be 4x and 3x years.
Sum of the present ages = 80 − 10 = 70 years
ATQ,
(4x + 3x) = 70
7x = 70
So, x = 10
So, difference between their present ages = (4x − 3x) = x = 10 years
