Question

How many times does the 28th day of the month occur in 400 consecutive years

Answer 1

Answer:

Consider a set of every four years (So as to include the leap year with Feb 29). So in 3 years, 29 will occur 11 times, and once it would accur 12 times. So in 4 years, there will be 3*11 + 12 = 45 days in which you will have 29th. So in 400 years, it would be 4500 times.
