Albert, Bernard and Carl go to eat frecuently. Each one order Tea or coffee after eating.
If Albert order coffee, Bernard orders the same that Carl orders.
If Bernard orders cofee, Albert orders the drink that Carl have NOT ordered.
If Carl orders tea, Albert orders the same as Carl.
So, Who of them orders the same drink after eating?
Problem 2:
In the Triangle PQR we know that P`R=QR=12. We take S, at Page Ranking so RS=8.
We take T at QR so RT=8. PT П QS = N
Knowing that RSNT area is 8, Discover PQR triangle's area.
Problem 3:
A Geologist has some stones and no one of them weight more that 1Kg.
We knoq if we divide the stones in two groups, no matter the way they are divided, one of the groups is less or equal that 1Kg.
Nothing is known about the number of stones that the geologist has, and how many the stones weight.
Discover the maximus value that can have the weight of all the stones together.
Problem 1 seems impossible, problem 2 I'm working on now, and problem 3 seems... well, I have no clue what I'm supposed to do, or if there's enough information about it =/
Any help about 1 and 3? (and possibly 2). I'm mostly wondering if I'm understanding the wording right when I say that
IF A = Coffee, B = C
IF B = Coffee, A =/= C
IF C = Tea, A = C
And, what is he trying to say when he said #3? =/
EDIT: also, is there enough info to solve #2? T_T
And I give up on solving it. I just am getting nowhere =/
Thanks mucho ^_^
