Verified Answer
The following is the availability of six security guards to guard a mu...
Murugan works on Saturdays if the head of the security staff makes a special request.
There are 4 guards required on each day.
Mariappan, Murali and Murugesh are available for work on all Saturdays. Thus, the fourth guard would be selected from Mani and Murugan.
Mani is available on the 1st and 3rd Saturdays.
Thus, the head of the security staff will have to definitely make a special request when it is certain that Mani will not come i.e. on all 2nd and 4th Saturdays.
On the 1st and 3rd Saturday of each month, Mani may or may not come.
Therefore, the head may not need to call Murugan on those Saturdays.
Now, to maximise the number of Saturdays, assume that the given year is a leap year and that there are 53 Saturdays.
Now, number on Saturdays on which Mani may be present = 24 . Maximum number of days on which the special request definitely has to be made = 29.
Hence, option 3
