Kaplan Box Logic Game question Forum

[Hannibal]

Hey,

I've got that box of Kaplan logic mini-games and I can't figure out how they figured this.

Each of three friends, Ali, Ben and Cassandra, orders at least one of the following three flavors of ice cream: pistachio, strawberry, and vanilla. No other flavors of ice cream are available, and the orders must be made in accordance with the following conditions:

Ali and Ben cannot order the same number of flavors.

Cassandra cannot order as many of the flavors as Ali does.

Anyone who orders pistachio must also order vanilla.

Which flavor of ice cream cannot be ordered by Ben?

The answer is pistachio, because "Ben can only order one flavor" and anyone who orders pistachio must also order vanilla.

I don't get why Ben can only get one flavor. Let's say Ali gets three flavors and Cassandra gets one. Ben can get two, right?

You're right. According to the rules you listed, the following two scenarios are valid:
A: P S V
B: P V
C: _

A: P S V
B: P V
C: _ _

On the other hand, if the first rule had specified that A and B do not order any of the same flavors, then the distribution would be fixed at 2, 1, 1 for A, B, and C respectively.

So, it's Kaplan's mistake.

Bastages.
