How many odd days are in 15 years?
Answer: 100 years give us 5 odd days as calculated above. 200 years give us 5 x 2 = 10-7 (one week) => 3 odd days. 300 years give us 5 x 3 = 15-14 (two weeks) => 1 odd day.
How are there 5 odd days in 100 years?
Concept of Odd Days In a century – i.e. 100 years, there will be 24 leap years and 76 non-leap years. This means that there will be 24 x 2 + 76 x 1 = 124 odd days. Since, 7 odd days make a week, to find out the net odd days, divide 124 by 7. The remainder is 5.
