Question

In a queue, A is eighteenth from the front while B is sixteenth from the back. If C is twenty-fifth from the front and is exactly in the middle of A and B, then how many persons are there in the queue?

Options

• 45

• 46

• 47

• 48

Answer 1

47

Explanation:

A is positioned 18th from the front, and C is positioned 25th.

The number of people between A and C is 6.

Because C is exactly in the middle of A and B, the number of people between C and B equals 6.

\[\ce{\overset{17}{<->}A \overset{6}{<->}C \overset{6}{<->}B \overset{15}{<->}}\]

Number of Persons in the queue = (17 + 1 + 6 + 1 + 6 + 1 + 15) = 47.
