Correct answer: (A) 50897
Explanation
The total is 50897, so the answer is 50897.
In 2020 types A, B and C are 17, 18 and 17 percent of 48600.
Together that is 52 percent of 48600, which is 25272.
In 2021 types A, B and C are 18, 15 and 8 percent of 62500.
Together that is 41 percent of 62500, which is 25625.
