Answer 1

14 masks

 

"none was blue"   means       blue=0  red=14

"one was blue" means          blue=1  red=13

 

"Some were blue" could mean:

   blue     red

     2        12

     3        11

     4        10

     5          9

     6          8

     7          7

     8          6

     9          5

    10         4

    11         3

    12         2

    13         1

 

Now, you must decide whether "the rest were red" could mean:     blue=14  red=0
