Pretty tricky problem but the based idea is that the inspection is happening on a given set days. The stem does not mention that the inspection will happen on ALL days of the given month.
Statement 1:
Inspection conducted on five tuesdays.
This means that particular month is having ATLEAST 29 days. Now it could be 30 or 31 too. AND the inspection could have for only 29 days out of 30/31 we dont know.
If we have a Tuesday on the very first day, then Monday is the previous month. Now one may conclude than the current month of Tuesday is having 29 days thus previous month is a January and thus 31 days, BUT NO. We dont know if the current inspection month is having 29/30/31 days yet.
Even then the previous month is of little relevance but its important to note the subtlety nonetheless.
INSUFFICIENT.
Statement 2:
4 thurs and 4 sats.
Now try including 5 mondays, sure one will conclude that its possible for sure since if you consider a 31 day month its definitely possible.
BUT is it for certain?
I can have 4 sat and 4 thurs and 5mondays in THAT month and still do inspection NOT on 5 mondays.
Like I mentioned in statement 1, inspection on all days of a month is NOT a certainty.
INSUFFICIENT.
Combining the two:
Include 5 tuesdays, lets keep it as 2nd, Monday as 1st, Thursday and Saturday on one of the days.
I can do inspection starting from 2nd covering 5 tuesdays, 4 thursdays and 4 saturdays and still skip 5 mondays.
INSUFFICIENT.
