The difference between the ages of two friends is 2 years. The sum of their ages is 74 years. Find the age of the older friend.
The age of the older friend is half of the sum of the sum and the difference.
Did I give you a headache?
Age of the older friend = (74+2)/2=38
See if you can figure out how to calculate the age of the younger friend?posted by MathMate
