The present average age of Rachel and Ross is 34 years. Find the average age of Ross and Rachel after 6 years.
Solution
The present average age of Rachel and Ross is 34 years.

Sum of the ages of Rachel and Ross after 6 years = (68+6+6) years
= 80 years
The average age of Ross and Rachel after 6 years = $$\frac{80}{2}$$
= 40 years
