The average age of Andras, Frances and Gerta is 22 years. What is Gerta's age?
(A) 19
(B) 20
(C) 21
(D) 22
(E) 23

| Name | Age (Years) |
| :---: | :---: |
| Andras | 23 |
| Frances | 24 |
| Gerta | $?$ |
Since the average of the three ages is 22 , then the sum of the three ages is $3 \cdot 22=66$.

Since Andras' age is 23 and Frances' age is 24, then Gerta's age is $66-23-24=19$.

ANSWER: (A)
