1/
5 of the T-shirts are red.
3/
10 of the red shirts are small.
Implication of the denominators in blue:
The total number of shirts must be a value that can be divided first by 5 (to calculate the number of red shirts) and then by 10 (to determine how many of the red shirts are small).
Thus, the total number of shirts must be a MULTIPLE OF 50.
The correct answer is
E.
