Given:
The number of years = 2120
To find:
The number of odd days in the first 2120 years
Solution:
2120 = 2000 + 100 + 20
= 400*5 + 100 + 20
Number of odd days in 100 years = 5
Number of odd days in 400 years = 4 x 5
= 20 days + 1 (+1 as 400 is a leap year itself)
= 21 days
= 0 odd days (divide 21 by 7 we get remainder 0)
Number of odd days in 2100 - 2120 = 21 days
= 0 odd days
The total number of odd days = 0+5+0
= 5 days
Hence, the number of odd days in 2120 years is a) 5.
