anonymous · Answer

Jack and James ages are in the ratio of 5:6. After 10 years their age will be in the ratio of 6:7. What are their Present ages?

mathstudent55 · Answer

Ok. Now everything relates to ages, so we can solve it.

anonymous · Answer

now it is a right question

mathstudent55 · Answer

Let's say Jack is x years old now.
Also, we'll say James is y years old now.
Since the ratio of their ages is 5:6, we can write an equation:
x/y = 5/6
Ok so far?

mathstudent55 · Answer

In 10 years, each one is 10 years older.
In 10 years, Jack will be x + 10 years old.
In 10 years, James will be y + 10 years old.
In 10 years, the ratio of their ages is:
(x + 10)/(y + 10) = 6/7

mathstudent55 · Answer

Now we have a system of equations. We want to solve for x and y, the present ages.
