Okay here is the riddle,
There are 7 days in a week : Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, Sunday.
DR.V tell lies on Wednesday, Friday, Saturday and tell truth on other days.
Prof.V tell lies on Monday, Thursday, Friday, Sunday and tell truth on other days.
One day, they BOTH said " I tell lies yesterday "
Which day is it ??

To make it simpler im providing m/c answers :
A. Saturday
B. Tuesday

Saturday and wednesday are the days they were supposed to have both lied on so the answer is Thursday and Sunday I think!!

[DR.V]

Hmm maybe ...

[DR.V]

Hehehe

they are both born liers...saturday....unless they were doing it again

[Chafule]

hey thursday isnt in A,B,C,D lol

[vishy]

it has to be thursday and sunday. if the day falls on a day they were lying the previous day must be a day the were telling the truth. and if the day falls on a day they were telling the truth obviously they had to be lyin the previous day if that makes sense.

Last year at uni I did philosophy, we took aguments and made them into maths statements. I was terrible at it, your problem reminds me of this. What kind of degree are you doing?

[cat_2785]

it took my boyfriend around less than 10 minutes. For some reason he always gets the right answer to these sorts of things.

I cant really write it here, coz it uses weird symbols that our keyboard doesnt have... :( not making excuses here LOL

[jim from sydney]

well try to write it for yourself anyway, make it work with equation editor (excel) and let us know when it works correctly, then you can give it to those who are interested, thru' their individual e-mail addresses....mathematical riddles are fun don't you think ??? :blob Jim
