Question
If Republic day was celebrated in 1996 on Friday, on which day in 2000 Independence day was celebrated?
Answer: Option B
Answer: (b)
Number of days in 1996 (366-26) = 340
Number of days in 1997 = 365
Number of days in 1998 = 365
Number of days in 1999 = 365
Number of days from January 2000 to July 2000 = 31 + 29 + 31 + 30 + 31 + 30 + 31
= 213
Number of days from 1st to 15th August, 2000 = 15
∴ Total days = 340 + 365 + 365 + 365 + 213 + 15 = 1663
∴ 1663 ÷ 7 = remainder 4
∴ 1663 days = (237 X 7 + 4) days = 237 weeks + 4 days
∴ Number of odd days = 4
∴ Day on 15th August, 2000 = Friday + 4 Odd days = Tuesday
