Brainercise: Jessica M edition version 2.0

It’s that time again! My answer to Jessica M’s first brainteaser is comment #3.  I’ll update this post with Jessica M’s answer once it’s up.  In the meantime, here’s her next brainteaser. Thanks Jessica!

Sarah, Lucy, Albert, Edward, Jennifer, and Roger are siblings.  To go to school they use three different buses: the blue one, the red one, and the yellow one.  They always go in pairs.  Albert does not go in the red bus because he accompanies Edward who doesn’t go in the blue bus.  Roger travels in the blue bus.  If Lucy neither accompanies Jennifer nor uses the blue bus, in which bus does Sarah go to school?

okay… sarah rides the red bus

so its albert and edward ride in the yellow bus…
therefore roger and jennifer ride in the blue bus and lucy and sarah ride together in the red bus…

assuming edward doesnt ride the blue bus and albert doesn’t ride the red bus.. whats left is the yellow bus since they travel as a pair…

then you have everyone else out for the yellow bus…

Then rodger does ride in the blue bus… so you got that down…and then you see that lucy doesn’t ride the blue bus… therefore the only other bus left would be the red bus…

Lucy doesn’t accompany jennifer… and Lucy rides the red bus therefore Jennifer doesn’t ride the red bus… but the blue bus with rodger…

then you have sarah left… and you know that lucy rides the red bus…
and since they ride in pairs that is the only bus left…
therefore sarah rides in the red bus with Lucy

and voila :D
yeahh i kinda did it in my head which was amazing and then i had to write it out to make sure like jess did

wooo

hello Kathy,
Apparently you really like brain exercises… :)

I have one for you:
“A man is in a car. There is no moon, no lights on the side of the road and fires of his car are put out. However, when somebody, dressed in black, walk across the road… the car stopped. What’s happened ? How the man could see that somebody crossing the road? ”

I have another one:
“A boy is in a car with is father. They suddenly have a car accident. The father unfortunatly dies in that accident and the boy is rushed to a hospital. The doctor who must operate on the boy, see the boy and says:” I can’t operate on him, he is my son”… How it is possible?”

I wait for your ideas and proposals. :)
Good luck
xoxo

Yea Sarah is on the red one.. I promise I didn’t look at the comments!
And I had to draw this little story out too, as I was mucho confused.. Feels like my brain just did 5 push-ups, cool! thanks Kathy!

I agree with everyone! Red! Like the love I have for all of you! ;)

Sarah is on the red bus.

Albert and Edward are on the yellow bus because they accompany each other. They can’t be on the red bus because Albert isn’t on the red bus, and they can’t be on the blue bus because Edward isn’t on the blue bus. So that just leaves the yellow bus for them.

Lucy is on the red bus with Sarah because it says Lucy isn’t on the blue bus, and she can’t be on the yellow bus because Albert and Edward are on the yellow bus. So that leaves the red bus for Lucy. Lucy is with Sarah because Albert and Edward are on the yellow bus, Roger is on the blue bus, and she’s not accompanied by Jennifer. So that leaves only Sarah. Ta da!
