B) 5th, 12th, 19th, 26th
C) 3rd, 10th, 17th, 25th
D) 4th, 11th, 18th, 25th
E) None of the above
Correct Answer: B
Solution :
| First, we find out the day on 1.03.2005, Period upto 1.3.2005 = (yr 2004 + Period from 1.1,2005 to 1.3.2005) |
| \[\therefore \] Odd day in 1600 yr = 0 |
| Odd day in 400 yr = 0 |
| 4 yr = (1 leap year + 3 ordinary years) |
| \[=(1\times 2+3\times 1)=5\]odd days |
| Number of days between 1.1.2005 to 1.3.2005. |
| January + February + March = 31 + 28 + 1 = 60 days |
| = (8 weeks + 4 days |
| = 4 odd days |
| Total number of odd days \[=(0+0+5+4)=9\] |
| = 1 week + 2 days |
| = 2 odd days |
| \[\therefore \]1.3.2005 was Tuesday. |
| So, Saturday will fall on 5.3.2005. |
| Hence, Saturday lies on 5th, 12th, 19th and 26th of March 2005. |
