Aptitude - Calendar - Discussion

Tell me different shortcut methods for different problems given on clerical exam papers?

Eg: Today is 1st Monday, so after 7 days i.e. 8th is Monday so
From the given question: Today is Monday after 61 days it will
be Friday.

Sol: In 61
8*7=56 i.e. 57th is Monday
58 --- tue
59 --- wed
60 ---- thursday
61 ----- Friday

Today is Monday Each day of the week is repeated after 7 days.

So fist day and 8th day is same.

So Today is Monday mean 56th day is Monday.

So answer is Saturday (process:- 8*7=56, 56th day is common ga Monday:, so 57th:-the, 58:-wen, 59:-thu, 60:-fri, 61:-sat).

Monday = 1 odd day.

61 days = (8 weeks + 5 odd days).

= 5 odd days.

Total odds = 1 + 5 odd days.

= 6.

Number 6 mentions Saturday.

If week start with Monday, so it ends with Sunday, not Sunday, hence at 63rd day it will be Sunday. So at 61st it will be Friday.

Another question to further explain the above statement

What will be day after 366 says(keeping today as monday)??
subtracting it from 392.
392-366=26.
26/7=3.5/7( where 3 is quotient.
5 is remainder.
7 is divisor.)
now moving back 5 days (because of remainder).
it will be thursday.
another way to calcultae thursday.
as 7*4=28
but the diff is 26
28-26=2
moving ahead(instead of backward) from monday,it will tuesday first then wednesday but the third day will be thusday so we add
2 days to manday and the result will be the third day.

I hope it works.

Its upto to your choice what you choose(backward or ahead).
