Q:

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?

A) 41	B) 40
C) 28	D) 27

Answer & Explanation Answer: C) 28

Explanation:

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: $\overset{3}{\leftarrow} C \overset{8}{\leftrightarrow} B \overset{5}{\leftrightarrow} A \overset{21}{\to}$

Clearly, number of persons in the queue = (3+1+8+1+5+1+21=) 40

Case II: $\overset{3}{\leftarrow} C A \overset{5}{\leftrightarrow} B$

Number of persons between A and C

= (8 - 6) = 2

$∵ [C \overset{8}{\leftrightarrow} B A \overset{21}{\to} B]$

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.
