The Average of Three

There are three numbers. The first two are 2/3 and 3/4.

What does the third number have to be to make the average of all three be 2?

4 7/12

In order for the average of three numbers to be 2, they must all add up to 6. That gives you this equation:
2/3 + 3/4 + n = 6

Solve for n = 55/12, or 4 7/12.

Petals Around the Rose

Here are five rolls of dice, with their score.

Roll #1 – Score: 6

Roll #2 – Score: 4

Roll #3 – Score: 4

Roll #4 – Score: 8

Roll #5: 0

This is what you know:

1. The name of this game is significant (Petals Around the Rose)
2. The answer is always even

How is the score determined?

The solution is to count the dots (petals) surrounding the center dot (the rose).

Only odd numbers have a center dot, so even numbers (2, 4 and 6) are worth zero.

1 doesn’t have any surrounding dots, so it too is worth zero.

The three has two dots surrounding the center, so it’s worth two.

A five has four petals around the rose making it worth four.
