If B is the median, then two of the others must be older and two must be younger. A is one of the older because she is the oldest of the 5, and C is older because that fact is given. That means that E is second to the youngest because D is youngest.
So we have them in order of age from youngest to oldest:
D E B C A
Since the sum of their ages is 110 and C is the mean age, C is 110 divided by 5, or 22.
Since D is 19 and they are all different ages, E and B must be 20 and 21 respectively.
The sum of the ages of D, E, B, and C is 82. 110 minus 82 is 28. Therefore:
D is 19
E is 20
B is 21
C is 22
A is 28

Work out the age of each person.
:
Find Caroline's age who is the mean
= 22 yrs
:
The ages from oldest to youngest using the information given
A - C(22) - B - E - D(19)
It has to be
A - C(22) - B(21) - E(22) - D(19)
Find A
A = 110 - 22 - 21 - 20 - 19
A = 28 yrs

Ashley is 28
Brian is 21
Caroline is 22
Elaine is 20
