Question 2

Three persons A, B and C are standing in a queue. There are five persons between A and B and eight persons between B and C. If there be three persons ahead of C and 21 persons behind A, what could be the minimum number of persons in the queue?

Accepted Answer

Three persons A, B, C can be arranged in a queue in six different ways, ie ABC, CBA, BAC, CAB, BCA, ACB. But since there are only 3 persons ahead of C, so C should be in front of the queue. Thus, there are only two possible arrangements, ie CBA and CAB. We may consider the two cases as under: Case I: ← 3 C ↔ 8 B ↔ 5 A → 21 Clearly, number of persons in the queue = (3+1+8+1+5+1+21=) 40 Case II: ← 3 C A ↔ 5 B Number of persons between A and C = (8 - 6) = 2 ∵ [ C ↔ 8 B A → 21 B ] Clearly number of persons in the queue = (3+1+2+1+21) = 28 Now, 28 < 40. So, 28 is the minimum number of persons in the queue.
