Solution to Puzzle L-4.  SUMMER READINGS

Bill, Frank, Cathy, Dolly and Jill read three of the following books last summer:

The Hobbit, Speak, The Lorax, To Kill a Mockingbird, and Little Women.

To solve this puzzle, create a table below with Y representing the books read, and X representing the books not read.

Bill and Frank did not read Little Women.

Cathy did not read The Hobbit.

Based on the above we have

 

Hobbit

Speak

Lorax

Mockingbird

Little Women

Bill

Since we know the two books Bill, Frank, and Cathy did not read, we know the three books each of them read.

PRIME NUMBERS

Prime numbers have captured the hearts of many mathematicians for centuries.  During 18th century, mathematician Christian Goldbach (1690-1764) wrote to Leonhard Euler that he believed it could be shown that every even integer greater than 2 is the sum of 2 primes.  For example, 30 = 23+7 and  36 = 13+23.  Until now, this conjecture has neither been proved or disproved.
