A question that I don't understand in my Uni course

I got a question as follows

Four processes - A,B,C,D are ready to execute, having arrived in this order

A - 2 Quanta - priority 1 (Lowest)

B - 4 Quanta - Priority 4 (Highest)

C - 5 Quanta - Priority 2

D - 3 Quanta - Priority 3

How many quanta are required for each process (A,B,C,D) to terminate under round-robin scheduling?

I'm not entirely sure what this is asking as it's my first year and I'm just starting …

course cybersecurity don order processes quanta question understand
