Solution

The correct option is D 27
A leap year has 52 weeks (i.e. monday, tuesday ........)
So, there will be 52 Mondays fixed.
Number of days left =36652×7=2
Number of days in last week =2
So, the probability of a Monday in the week =27
Thus, the probability of 53 Mondays is 27.
Hence, option B is true.
