How many leap years are there in 800 years?

Answer 1

A leap year is every 4 years and so 800/4 = 200

... unless it includes a year that is exactly divisible by 100. In that case, an additional rule has to be applied. If a year is exactly divisible by 100 but not exactly divisible by 400, then it is NOT a leap year. If it is exactly divisible by 400 then it IS a leap year. 1700, 1800, and 1900 were NOT leap years. 2100, 2200, and 2300 will NOT be leap years. 1600, and 2000 were leap years. 2400 will be a leap year.

... so if the 800 year span happens to include a year exactly divisible by 100 but not exactly divisible by 400 then there would only be 199 leap years.

Answer 2

200 divided by 4 that is 50 leap years

Any 200-year period has either 48 or 49 leap years, depending on whether or not the period includes a year that is evenly divisible by 400 (any 400-year period always has 97 leap years).

Answer 3

The average number of leap years in any 200-year period is 48.5.

Answer 4

800/4=200

But 100th 200 300 500 600 700 year is not a leap year because it is not divisible by 400.

So required leap year =200-6=194

Answer 5

800

Answer 6

97.
