Question

Accepted Answer

(B) 19. Explanation: P is 7th from front. Q is 9th from back. Between them = 3. Total = 7 + 3 + 9 - 1 = 18. Wait: positions from front for P=7, from back for Q=9. If P is before Q: total = P_pos + gap + (total - Q_from_back + 1)... Let's use: total = P_from_front + people_between + people_after_Q = 7-1 + 3 + 9 = 19.
