Correct Option: C

As we know that ,
2 October 1869 means = 1868 complete years + 9 months + 2 days
1600 years give 0 odd days
200 years give 3 odd days

Number of leap years in 68 years = largest integer less than	68	= 17	.
	4

∴ 68 years contain 17 leap years and 51 non‑ leap years:
∴ 68 years have [ ( 2 × 17 ) + 51 ] = 85 days = ( 12 x 7 + 1 ) = 1 odd day
Also count number of days from January 1, 1869 to October 2, 1869 = January + February + March + April + May + June + July August + September + October = 31 + 28 + 31 + 30 + 31 + 30 + 31 + 31 + 30 + 2 = 275 days = 39 weeks + 2 days
∴ This gives 2 odd days
∴ Total number of odd days = 0 + 3 + 1 + 2 = 6
Hence , Day on October 2, 1869 was Saturday.
