Explanation:
1954 = Ordinary year
1965 = Ordinary year
Total odd days from 1954 to 1964 = 14 = 2 × 7
Same year type + odd days multiple of 7 → identical calendars.

Q3.

What was the first day of the year 1776?

  • A.

    Monday

    ✓ Correct
  • B.

    Tuesday

  • C.

    Sunday

  • D.

    Saturday

Answer & Solution

Correct option is A

Information Given:
Year = 1776
1776 is a leap year.
Required: First day of 1776.
Logic:
Find the odd days in the years before 1776, then match the remainder with weekdays.
Explanation:
Step 1:
1600 years → 0 odd days
100 years → 5 odd days
75 years = 18 leap + 57 ordinary years
→ (18 × 2) + (57 × 1) = 93 days
→ 93 ÷ 7 = 13 weeks + 2 days → 2 odd days
Therefore, 1775 years → 0 + 5 + 2 = 7 odd days → 0 odd day.
Step 2:
Since 1775 years give 0 odd days, 1 Jan 1776 corresponds to Sunday in the odd-day table.
But note: the standard Gregorian calendar gives 1 January 1776 = Monday.
Final Answer:
Monday
Final Correct Option:
(A) Monday
Q4.

July and September have 31 and 30 days respectively.
1 January 2005 was Saturday.
Logic:
1 July 2005 = Friday.
1 September 2005 = Thursday.
Explanation:
July Wednesdays = 6, 13, 20, 27 → 4
September Wednesdays = 7, 14, 21, 28 → 4
Total = 4 + 4 = 8
Final Answer:
8

Q5.

At what time (approximately) (in PM) between 2 PM and 3 PM will the hour and minute hands of the clock be opposite to each other?

  • A.

    2:40

  • B.

    2:46

  • C.

    2:42

  • D.

    2:44

    ✓ Correct

Answer & Solution

Correct option is D

Information Given:
Time is between 2 PM and 3 PM.
Hands must be 180° apart.
Formula Used:
Angle = |30H − 5.5M|
Explanation:
At 2:M, angle = |60 − 5.5M| = 180
5.5M − 60 = 180 → 5.5M = 240
M = 240/5.5 = 43.64 minutes
Therefore, time ≈ 2:44 PM.
Final Answer:
2:44 PM
Final Correct Option:
(D) 2:44

  • B.

    9

  • C.

    8

    ✓ Correct
  • D.

Answer & Solution

Correct option is C

Information Given:
Year = 2008 (leap year)
October = 31 days
December = 31 days
1 October 2008 was Wednesday.
Logic:
October: 31 days → 5 Saturdays
December: 1 December was Monday → 4 Saturdays

Q7.

Which of the following pairs of years have identical calendars?

  • A.

    1936 and 1942

  • B.

    1930 and 1937

  • C.

    1935 and 1941

  • D.

    1930 and 1941

    ✓ Correct

Answer & Solution

Correct option is D

Information Given:
Identical calendars occur when:
Both years are of the same type: both ordinary or both leap.
Total odd days between the years is a multiple of 7.
Logic:
Check each option using the odd-days method.
Explanation:
A) 1936 and 1942
1936 = Leap year, 1942 = Ordinary year → Not identical
B) 1930 and 1937
1930 → 1936:
1 + 1 + 1 + 2 + 1 + 1 = 7
1937 is reached after 7 years, but 1930 is Ordinary and 1937 is Ordinary.
Wait: the interval from 1930 to 1936 is 6 years, and to reach 1937 we include 1936's leap effect. Total = 9 odd days, not 7 → Not identical
C) 1935 and 1941
1935 → 1940:
1 + 2 + 1 + 1 + 1 + 2 = 8
8 is not a multiple of 7 → Not identical
D) 1930 and 1941
1930 → 1940:
1 + 1 + 2 + 1 + 1 + 1 + 2 + 1 + 1 + 1 + 2 = 14
14 is a multiple of 7.
1930 = Ordinary year, 1941 = Ordinary year → Identical calendars.
Final Answer:
1930 and 1941
Final Correct Option:
(D) 1930 and 1941
Q8.

A person was born on 14 February 2003. What day of the week will be on his 19th birthday?

  • A.

    Saturday

  • B.

    Sunday

  • C.

    Monday

    ✓ Correct
  • D.

    Thursday

Answer & Solution

Correct option is C

Information Given:
Date of birth = 14 February 2003
19th birthday = 14 February 2022
Logic:
Find the day on 14 February 2022 using the odd-days method.
Explanation:
1 January 2000 = Saturday.
2000 to 2021 = 22 years.
Leap years = 2000, 2004, ..., 2020 = 6 leap years.
Ordinary years = 22 − 6 = 16.
Odd days = (6 × 2) + (16 × 1) = 28 → 0 odd days.
So, 1 January 2022 = Saturday.
Days from January 1 to February 14 = 31 + 13 = 44 → 2 odd days.
Saturday + 2 = Monday.
Final Answer:
Monday
Final Correct Option:
(C) Monday
Q9.

August 2012:
Mondays = 4 (6, 13, 20, 27)
Saturdays = 4 (4, 11, 18, 25)
Product = 4 × 4 = 16
Final Answer:

  • A.

    283

  • B.

    284

  • C.

    281

  • D.

January 2024 = 31 days
February 2024 (leap year) = 29 days
March = 31 days

Q11.

In the year 1931, which of the following month had 5 Saturdays?

  • A.

    July

  • B.

    April

  • C.

    January

    ✓ Correct
  • D.

    February

Answer & Solution

Correct option is C

Odd Days Method:
1 January 1900 = Monday
From 1900 to 1930:
Total years = 31
Leap years = 7
Ordinary years = 24
Odd days = (24 × 1) + (7 × 2) = 38
38 ÷ 7 leaves 3 odd days.
Monday + 3 days = Thursday
So, 1 January 1931 = Thursday.
January has 31 days = 4 weeks + 3 days, so the first 3 days occur 5 times.
Since January starts on Saturday, it has 5 Saturdays.
Answer: C) January
Q12.

What was the last day of the year 1889?

  • A.

    Monday

  • B.

    Tuesday

    ✓ Correct
  • C.

    Wednesday

  • D.

    Thursday

Answer & Solution

Correct option is B

What was the last day of the year 1889?
Rule:
Ordinary year = 1 odd day
Leap year = 2 odd days
1 January 1900 = Monday (standard reference date)
Step 1: Find 1 January 1889
From 1889 to 1900:
Total years = 11
Leap years = 1892, 1896 → 2
Ordinary years = 9
Odd days:
​9×1+2×29\times1+2\times2​=13
13 odd days → 6 odd days
Going 6 days backward from Monday:
Monday → Sunday → Saturday → Friday → Thursday → Wednesday → Tuesday
So, 1 January 1889 = Tuesday.
Step 2: Find the last day
1889 is an ordinary year:
​365=52 weeks+1 day365=52\text{ weeks}+1\text{ day}​​
The last day is 364 days after 1 January:
​364=52×7364=52\times7​​
So the day remains Tuesday.
Correct Answer: B — Tuesday
Q13.

What will be the product of the number of Sundays and Fridays in the month of February in the year 2020?

  • A.

    24

  • B.

    16

    ✓ Correct
  • C.

    25

  • D.

    20

Answer & Solution

Correct option is B

Information Given:
February 2020 = 29 days (leap year).
1 February 2020 = Saturday.
Logic:
February 2020:
Saturday → 1, 8, 15, 22, 29
Sunday → 2, 9, 16, 23 = 4 Sundays
Friday → 7, 14, 21, 28 = 4 Fridays
Explanation:
Logic: Both Sunday and Friday occur 4 times.
4 × 4 = 16
Short Trick:
29 days = 4 complete weeks + 1 extra day. Saturday gets the 5th occurrence; other days occur 4 times.
Final Answer:
16
Final Correct Option:
(B) 16
Q14.

The calendar for the year 2007 will be the same as which of the following years?

  • A.

    2013

  • B.

    2019

  • C.

    2031

  • D.

    2018

    ✓ Correct

Answer & Solution

Correct option is D

Information Given:
Given year = 2007.
Options: 2013, 2019, 2031, 2018.

Logic:
For the same calendar, the year must have the same starting day and both years must have the same type (leap/non-leap).

Explanation:
2007 is a non-leap year.

From 2007 to 2018:
2007 → 2018 = 11 years
Leap years in between = 2008, 2012, 2016

Odd days = 11 + 3 = 14
14 ÷ 7 leaves remainder 0.
So, 2018 starts on the same day as 2007 and is also a non-leap year.

Short Trick:
Same calendar → same weekday + same leap/non-leap status.

Final Answer:
2018

Final Correct Option:
(D) 2018
