CAT Introduction to Selections and Distributions - Practice Questions & MCQ

Directions for question:

In the recent past in Kolkata, the abduction of primary school children, which was unheard of before, suddenly was on the rise. The Police Commissioner of Kolkata IPS Mr Vineet Kumar Goyal, instructed all the schools in Kolkata to take steps to increase the security of their students during school hours.

St Xavier’s School, Kolkata, already had a security system in place. However, the management, after a survey, decided to beef up the security at Gate D on Short Street, which was rather a secluded area. The management took the decision that there must be two guards guarding Gate D each day of the week from Monday to Saturday. The security agency they did business with sent five top security guards named Ambar, Biplab, Chandan, Dinesh and Ekram for the job. 

However, they had some constraints while performing their duty :

a) None of the guards worked for three consecutive days in a week

b) Ambar did not work on Monday, Tuesday, and Wednesday

c) Biplab and Dinesh both had a service gun and hence never worked on the same day

d) Biplab worked on alternate days and he worked with Ambar on Friday

e) Ekram worked for the maximum number of days in a week amongst all the five guards

f) Both Biplab and Dinesh worked for an odd number of days during the week

g) Two particular guards out of the five worked for the same number of days in a week

h) Each of the rest three guards worked for a distinct number of days

Question: If Ekram worked with one particular guard twice during a week, then which guard worked on the same day as Dinesh?
