respectively. What is the average time per call?

a) 4 minutes b) 7 minutes c) 1 minute d) 5 minutes

11. A permutation is often represented by the cycles it has. For example, if we permute the

numbers in the natural order to 23154, this is represented as (132) (54) in this the (132)

Page 2: aptitude qns

say that the first number has gone to the position 3, the third number has gone to the

position 2, and the second number has gone to position 1, and (54) means that the fifth

number has gone to position 4 and the fourth number has gone to position 5. The

numbers with brackets are to be read cyclically. If a number has not changed position, it

is kept as a single cycle. Thus 52134 is represented as (1345)(2)

We may apply permutations on itself if we apply the permutation (132)(54) once, we get

23154. If we apply it again. We get 31245, or (123)(4)(5)
