Problema Solution
A boy is 1/4 as old as his father. In 5 years he will be 1/3 as old as his father will be. What are their present ages?
Answer provided by our tutors
x= father's age, y= son's age
(1/4) x = y
x=4y
(1/3) (x+5) = y+5
(x+5)= 3y +15
4y +5 = 3y +15
y=10, x=40
the son is 10 years old now, the father is 40 years old now
