Problema Solution
Shane is twice as old as his daughter. In 42 years, the ratio of their ages will be 4:3. What is the daughter's current age?
Answer provided by our tutors
let 'x' represent the daughter's age, then '2x' represents Shane's aget
Shane's age must be represented by '4' in the ration 4:3, so:
4/3 = (2x+42)/(x+42)
solving for 'x' we have x=21
the daughter's current age is 21
