What was the day of the week on 18 March 2020?
Tuesday
Wednesday
Thursday
Friday
Correct answer
Wednesday
Why this answer is correct
We need to find the day for 18 March 2020.
Completed years (2000 years + 19 years) + period from 1 January 2020 to 18 March 2020.
1. Odd days in 2000 years:
As 2000 is a multiple of 400 ⇒ 0 odd days.
2. Odd days in the remaining 19 years (2001 to 2019):
In 19 years, number of leap years = 19/4 = 4 (2004, 2008, 2012, 2016).
Number of ordinary years = 19 − 4 = 15.
Odd days = (4 × 2) + (15 × 1) = 8 + 15 = 23 days.
23 days = (23 ÷ 7) ⇒ 3 weeks + 2 odd days.
3. Odd days in 2020 (up to 18 March):
2020 is a leap year (divisible by 4).
January = 31 days
February = 29 days
March = 18 days
Total days = 31 + 29 + 18 = 78 days.
78 days = (78 ÷ 7) ⇒ 11 weeks + 1 odd day.
4. Total odd days:
Total odd days = 0 (from 2000 years) + 2 (from 19 years) + 1 (from 2020) = 3 odd days.
5. Mapping of the day:
According to the odd days count: 0 = Sunday, 1 = Monday, 2 = Tuesday, 3 = Wednesday, 4 = Thursday, 5 = Friday, 6 = Saturday.
Since the total number of odd days is 3, the day was Wednesday.
The day on 18 March 2020 is Wednesday.
Hence, the correct answer is “Option 2”.
Alternate Method
Using the formula: Day = (Date + Month Code + Century Code + Year + Year/4) ÷ 7
For 18 March 2020:
Date = 18
Month Code (March) = 4
Century Code (2000) = 6
Year = 20
Leap Year (20 ÷ 4) = 5
Total = 18 + 4 + 6 + 20 + 5 = 53
53 ÷ 7 ⇒ Remainder = 4
In this system (where 1 = Sunday, 2 = Monday, 3 = Tuesday, 4 = Wednesday), the code 4 corresponds to Wednesday.
Hence, the correct answer is Wednesday.
What will be the sum of number of days in the month of June, February, July and August in the year 2300?
120
119
121
122
Correct answer
120
Why this answer is correct
Checking the year 2300:
2300 ÷ 100 = 23 (It is a century year)
2300 ÷ 400 = 5.75
Since 2300 is a century year but is not divisible by 400, it is a common year.
Now, we list the number of days for each month in 2300:
Days in June = 30
Days in February (common year) = 28
Days in July = 31
Days in August = 31
Sum of the number of days = 30 + 28 + 31 + 31
Sum = 58 + 62
Sum = 120
Hence, the sum of the number of days in the month of June, February, July, and August in the year 2300 is 120.
Hence, the correct answer is “Option 1”.

Identify the wrong number in the following series.
3, 6, 11, 18, 27, 39, 51
18
27
39
51
Correct answer
39
Why this answer is correct
Logic followed here is,
3 + 3 = 6
6 + 5 = 11
11 + 7 = 18
18 + 9 = 27
27 + 11 = 38 ≠ 39
38 + 13 = 51
Hence, the correct answer is “Option 3”.
Two pipes can fill a tank in 12 hours and 18 hours, respectively. A third pipe can empty the tank in 9 hours. If all three pipes are opened together, in how much time will the tank be filled?
18 hours
36 hours
24 hours
12 hours
Correct answer
36 hours
Why this answer is correct
Given:
Two pipes can fill a tank in 12 hours and 18 hours.
A third pipe can empty the tank in 9 hours.
Formula used:
Time = Total Capacity ÷ Net Efficiency
Calculation:
Let pipes are A, B and C.
Efficiency of Pipe A = 36 ÷ 12 = 3 units/hr
Efficiency of Pipe B = 36 ÷ 18 = 2 units/hr
Efficiency of Pipe C = 36 ÷ 9 = 4 units/hr (Since it empties the tank, its efficiency will be taken as negative).
Net Efficiency = Efficiency of A + Efficiency of B − Efficiency of C
Net Efficiency = 3 + 2 − 4 = 1 unit/hr
Time = Total Capacity ÷ Net Efficiency
Time = 36 ÷ 1 = 36 hours
Hence, the correct answer is “Option 2”.

8149 : ? :: 5625 : 5584 :: 309 : 268
8104
8114
8106
8108
Correct answer
8108
Why this answer is correct
The logic followed here is:
Logic: Second Number = First Number − 41
For the second pair 5625 : 5584
⇒ 5625 − 41 = 5584.
For the third pair 309 : 268
