Q1: If the day after tomorrow is Thursday, what day was it yesterday?
(a) Monday
(b) Sunday
(c) Tuesday
(d) Saturday
Ans: (c)
If the day after tomorrow is Thursday, then tomorrow is Wednesday. So, yesterday was Tuesday.

Q2: If today is Friday, what day of the week will it be 350 days from today?
(a) Monday
(b) Tuesday
(c) Saturday
(d) Sunday
Ans: (b)
350 days = 50 weeks, so it will be the same day of the week, which is Friday, 350 days from today.

Q3: How many odd days are there in 900 years?
(a) 0
(b) 1
(c) 3
(d) 5
Ans: (a)
A year has 365 days, and 900 years have 900 * 365 = 328500 days. When you divide 328500 by 7 (the number of days in a week), you get a remainder of 2. Therefore, there are 2 odd days in 900 years, which means there are no odd days.

Q4: On which day of the week did India celebrate its first Republic Day on January 26, 1950?
(a) Thursday
(b) Friday
(c) Sunday
(d) Tuesday
Ans: (b)
January 26, 1950, was a significant day for India as it became a republic. To find the day of the week, we calculate the odd days:
January 26, 1950 = (1600 + 300 + 50) + 26 days = 1950 + 26 days = 1976 days
Since 1976 is evenly divisible by 7, there are no odd days. Therefore, India celebrated its first Republic Day on a Friday.

Q5: If today is Thursday, how many days are there until the next Friday?
(a) 6
(b) 7
(c) 8
(d) 9
Ans: (a)
If today is Thursday, then the next Friday is just one day away, so there are 6 days until the next Friday.

Q6: If March 2, 2040, is a Saturday, what day of the week will it be on March 2, 2050?
(a) Saturday
(b) Sunday
(c) Monday
(d) Tuesday
Ans: (b)
Since 2040 is a leap year, March 2, 2041, will be one day ahead (Sunday). For each non-leap year, it will advance one more day. Therefore, March 2, 2050, will be on a Sunday.

Q7: Which of the following is not a leap year?
(a) 2024
(b) 2100
(c) 2028
(d) 2032
Ans: (b)
A leap year occurs every 4 years, but century years (divisible by 100) are not leap years unless they are divisible by 400. So, 2100 is not a leap year.

Q8: If January 1, 2024, falls on a Monday, what day of the week will January 1, 2025, be?
(a) Tuesday
(b) Wednesday
(c) Thursday
(d) Friday
Ans: (c)
In a non-leap year, the day advances by one day. So, January 1, 2025, will be one day after January 1, 2024, which was a Monday, making it a Thursday.

Q9: A leap year is defined as:
(a) A year that is divisible by 4
(b) A century year divisible by 400
(c) A non-century year divisible by 4
(d) Both (b) and (c)
Ans: (d)
A leap year can be either a century year divisible by 400 (e.g., 2000) or a non-century year divisible by 4 (e.g., 2020).

Q10: How many odd days are there in 150 years?
(a) 0
(b) 1
(c) 2
(d) 3
Ans: (c)
In 150 years, there are 37 leap years (divisible by 4). Each leap year has two odd days. The remaining 113 years are non-leap years, each with one odd day. Therefore, the total odd days are 37 * 2 + 113 * 1 = 74 + 113 = 187, which is equivalent to 2 odd days.
