Table: Participants in a regional review session — Region I 120, Region II 80, Region III 200, NCR 400. What percentage of all participants came from NCR?

Correct answer: A. 50%

NCR share = 400 ÷ 800 × 100 = 50%. NCR alone had as many participants as the other three regions combined. The other three regions add up to 120 + 80 + 200 = 400, which confirms the 50% share.
