SOLUTIONS

1. Number of odd days in 95 days.
95/7 = 13 complete weeks + 4 odd days
A: 1

 

2. If 6th February 2012 is Sunday, first let us find out 14th November in 2012 is on which day.
Number of odd days from 6

February 2012 to 14th November 2012
Month: Feb + March + Apr + May + June + July + Aug + Sep + Oct + Nov.
Odd days: 2 + 3 + 2 + 3 + 2 + 3 + 3 + 2 + 3 + 0
23/7 = 2 odd days.
From 6th February 2012 to 14th November 2012 there are two odd days, hence 14th November 2012
is two days to Sunday i.e. Tuesday.
From 14th November 2012 to 14th November 2018, there are six years. Among these six years there is
one leap year and five non leap years. 7
i.e: (1 × 2 + 5 × 1) ⇒ (2 + 5) = 7/7 = 0 7
odd days in these six years.
Hence, 14th November 2018 will be on the same day as 14th November 2012 i.e. Tuesday.
A: 4

 

3. Number of odd days in 124 days

124/7 = 5 odd days
If today is Friday then five days back from today was sunday
A: 4

 

4. For every four years a leap year will come, 2096 + 4 = 2100 but 2100 is a century year and is not
divided by 400. So, 2100 is not a leap year. Hence, the next leap year after 2096 will be 2104.
A: 4


5. A leap year will have 366 days.
Number of odd days in a leap year
366/7 = 2 odd days.
Hence a leap year will have two odd days.
A: 2

 

6. A non leap year will have 365 days
Number of odd days in a non leap year
365/7 = 1odd day
Hence, non leap year will have only one odd day.
A: 4

 

7. As 1974 is not divided by 4, it is a non leap year. A non leap year will have only one odd day.
A: 2

 

8. The year 2100 is a non leap year, so 2100 will have only one odd day.
A: 2

 

9. The year 1956 is a leap year. So 1956 will have two odd days .

year and twenty days cannot be determined.
A: 4

 

11. Number of odd days from 15th January to 26th August in a leap year
Months: Jan + Feb + March + April + May + June + July + Aug
Days (odd days): 17(3) + 29(1) + 31(3) + 30(2) + 31(3) + 30(2) + 31(3) + 26(5)
Total odd days  = 22/7  = 1 odd day.
A: 1

 

12. As the year is a leap year or not is not clearly given. So, number of odd days cannot be determined.
A: 4

 

13. Number of odd days from 13th March to 19th October
Months: March + April + May + June + July + Aug + Sep + Oct
odd days: 4 + 2 + 3 + 2 + 3 + 3 + 2 + 5
Total odd days =
24/7  3 odd days.

A: 1

 

14. As the Year is a leap year or not is not clearly given So, number of odd days cannot be determined.
A: 4

 

15. Number of odd days from 20th November to 16th March
Months: Nov + Oct + Sep + Aug + July + June + May + April + March
Odd days: 5 + 3 + 2 + 3 + 3 + 2 + 3 + 2 + 2
25/7 = 4 Odd days

16. There are four years in between 1st January 2015 to 1st January 2019. In these 4 years, there are 3 non
leap years and 1 leap year.
3 non leap years will have − 3 × 1 = 3
1 leap year will have     −   1 × 2 = 2
                                      = 5
Hence, there are five odd days in these four years.
As 1st January 2015 is Wednesday then 1st January 2019 will be five days to Wednesday i.e. Monday.
A: 3

 

17. There are eight years between 1st January 2004 to 1st January 2012. In these eight years there are six
non leap years and two leap years.
A leap year will have two odd days = 2 × 2 = 4
A non leap year will have one odd day = 6 × 1 = 6
Hence, there are ten odd days in these eight years = 10/7 = 3 odd days
As 1st January 2004 is Wednesday then 1st January 2012 will be three days to Wednesday i.e. Saturday .
A: 1

A leap year will have two odd days = 24 × 2 = 48
A non leap year will have one odd day= 76 × 1 = 76
total odd days = 124
i.e.
124/7 = 5 odd days
Hence, there are five odd days in the first 100 years.
A: 3

 

19. 1400 years = 400 × 3 + 200 years
0 × 3 + 3 × 1 = 3 odd days
(100 years − 5 odd days
200 years − 3 odd days
300 years − 1 odd day
400 years − 0 odd day)
A: 4

 

20. 2700 years = 400 × 6 + 300 × 1
0 × 6 + 1 × 1 = 1 odd day
Hence, there is one odd day in the first 2700 years.
A: 2

 

22. There are three years between 28th January 2006 to 28th January 2009. In these three years there is one
leap year and two non leap years. A leap year will have two odd days and a non leap year will have one
odd day (i.e. 1 × 2 + 2,× 1 = 4). So, there are four odd days. If 28th January 2006 is Saturday then 28th
