2.The Toy Maker Game (Easy)

A toymaker will use six different paint colours—fuchsia,

goldenrod, heliotrope, indigo, jonquil, and khaki—to paint

three different model toys—an aeroplane, a race car, and a truck.

Each colour will be used once, and each toy will be painted with

exactly two colours. The following conditions apply:

Heliotrope and jonquil will not be used on the same model.

Either fuchsia or goldenrod, but not both, will be used on

the race car.

Indigo can be used only with either goldenrod or jonquil.

Goldenrod will not be used on the truck unless khaki is also

used on the truck.

which of the following must be true?

(A) Goldenrod must be used on the truck.

(B) Fuchsia must be used on the race car.

(C) Jonquil must be used on the aeroplane.

(D) Fuchsia and indigo must be used on the same

The example eliminates (A),(B),(C),(D)

Hence answer (E) is the right answer
