Wheel of Fortune
 
Q

A game wheel shows the numbers 1 to 36. Figure out on which 2-digit number Lucy has landed given the following facts:

The number is divisible by 3.
The sum of the digits in this number lies between 4 and 8.
It is an odd number.
When the digits in this number are multiplied together, the total lies between 4 and 8.


 

 
A Lucy has landed on 15. Make a list of numbers 1- 36 that are divisible by 3. Cross out all that are even. This leaves 9, 15, 21, 27, and 33. 9, 21, and 27 have a ?sum of digits? less than 4 or more than 8. But, 1 x 5 = 5 and 3x 3 = 9.

STRATEGY: Make a list and search for a pattern.
