A.

Saturday

B.

Friday

C.

D.

Answer with explanation

Answer: Option DExplanation

Always check that the given year is Leap Year or normal Year. If Leap Year and February encluded then the extra/ odd day of that Feb. month will be 1.If Normal Year and February encluded then the extra/ odd day of that Feb. month will be 0. ( As per table no-II).

Here, the day will be count after the given date(1 January). So after 1 January, we get 30 days for January month and complete Feb., Mar., and April up to 5 days.

Here, the day will be count after the given date(1 January). So after 1 January, we get 30 days for January month and complete Feb., Mar., and April up to 5 days.

The extra day of Jan =2 (If 30÷7, the remainder will be 2)

The extra day of Feb.=1(2024 is Leap Year and so Feb’s extra day is 1) ☆ SeeTable-II

The extra day of Mar =3

The extra day of April =5 (April month has only 5 days so the extra day is 5, less than 7)

Total extra days=11 ( Which is greater than 7, so again must divide by 7 to get a total extra day)

Therefore, 11÷7 provide the remainder 4. Hence 4will be the final extra day of whole period)

Now given day+4=Friday+4=Tuesday.

On what dates of March 2005 did Friday fall ?

A.

4,11,18&25

B.

5,12,19&26

C.

6,13,20&27

D.

7,14,21&28

Answer with explanation

Answer: Option AExplanation

First of all, we have to find the day on 01.03.2005

01.03.2005 = (2004 years + Period from 01.01.2005 to 01.03.2005)

Number of odd days in 2000 years = 0 —-(1)

Number of odd days in 4 years = 1 leap year + 3 ordinary year

= 1X2 + 3X1 = 5 days —-(2)

From 01.01.2005 to 01.03.2005, we have,

Jan-31days + Feb-28days + Mar-1day = 60days

= 8weeks + 4days = 4 odd days —-(3)

Adding (1),(2)&(3), we get,total no.of odd days = 0+5+4

= 9 days = 1 week + 2days = 2 odd days.

2 odd days corresponding to Tuesday.So 01.03.2005 was Tuesday. Therefore, Friday lies on 04.03.2005.

Hence, the dates of March,2015 on which Fridays fell are 4,11,18&25

What was the day of the week on 16th July,1776?

A.

Monday

B.

Tuesday

C.

Wednesday

D.

Thursday

Answer with explanation

Answer: Option BExplanation

16th July,1776 = (1775 years + Period from 01.01.1776 to 16.07.1776)

1775 = 1600 + 100 + 75

No.of odd days in 1600 years = 0 —-(1)

No.of odd days in 100 years = 5 —-(2)

No.of odd days in 75 years = 18 leap years + 57 ordinary years = 18X2+57X1=93days=13weeks+2days=2 odd days —-(3)

From 01.01.1776 to 16.07.1776, we have,

Jan-31days+Feb-29days+Mar-31days+Apr-30days+May-31days+Jun-30days+July-16days = 198days = 28weeks + 2 days = 2 odd days —-(4)

Adding (1),(2),(3) & (4), we get,

Total no.of odd days = 0+5+2+2 = 9days = 1 week + 2days = 2 odd days. 2 odd days corresponding to Tuesday

Hence, the day of the week on 16th July,1776 is Tuesday

The calendar for the year 2007 will be the same for the year?

A.

2014

B.

2016

C.

2017

D.

2018

Answer with explanation

Answer: Option DExplanation

For example,if our answer is 2018, we must have the same day on 01.01.07 & 01.01.18 and number of odd days from 01.01.07 to 31.12.17 must be zero. Let us check the same thing for each of the given options.

Option (a)2015: No.of odd days from 01.01.2007 to 31.12.2014 = 2 leap years + 6 ordinary years = 2X2+6X1 = 10days = 1week + 3days = 3 odd days[not correct]

Option (b)2016: No.of odd days from 01.01.2007 to 31.12.2015 = 2 leap years + 7 ordinary years = 2X2+7X1 = 11 days = 1 week + 4 days = 4 odd days [not correct]

Option (c)2017: No.of odd days from 01.01.2007 to 31.12.2016 = 3 leap years + 7 ordinary years = 3X2+7X1 = 13 days = 2 weeks + 1 day = 1 odd day [not correct]

Option (d)2018: No.of odd days from 01.01.2007 to 31.12.2017 = 3 leap years + 8 ordinary years = 3X2+8X1 = 14 days = 2 weeks + 0 day = 0 odd day [correct]

The last day of a century can not be

A.

Monday

B.

Sunday

C.

Tuesday

D.

Wednesday

Answer with explanation

Answer: Option CExplanation

From the notes given on this web page, we have

Number of odd days in 100 years (1st century) = 5

So, the last day of 1st century is Friday

Number of odd days in 200 years (2nd century) = 3

So, the last day of 2nd century is Wednesday

Number of odd days in 300 years (3rd century) = 1

So, the last day of 3rd century is Monday

Number of odd days in 400 years (4th century) = 0

So, the last day of 4th century is Sunday

This pattern is repeated

Therefore, the last day of a century can not be Tuesday or Thursday or Saturday.

A.

Monday

B.

Sunday

C.

Tuesday

D.

Wednesday

Answer with explanation

Answer: Option CExplanation

1988 april 4th to 1987 november 3rd we have 27+31+31+29+31+4 = 153 = 153/7 = 21 weeks + 6 odd days.

rnHere is where everyone got confused,As per rules we take

rn[0 -sun 1 -mon 2 -tues 3 -wed 4 – thurs 5 – fri 6 -sat]

rnAs no.of odd days = 6 you may think the answer is saturday…

rnBut here later date is given and former date is asked,so the solution should be something like this..

rnwe have six odd days which means that we are short of one day to get the complete week i.e.., november 2nd would be monday and hence november 3rd is tuesday

Answer: Option AExplanation

→ 4th June, 2002 = (2001 years + Period from 1.1.2002 to 4.6.2002)

→ Odd days in 1600 years = 0

→ Odd days in 400 years = 0
