Good thinking
Two brunettes and a blonde are driving in the desert when, all of a sudden, their car breaks down.
As none of them have any motoring knowledge, they decide to walk. Each of them decides to take one thing with her.
The first brunette takes some food in case she gets hungry, the second brunette takes some water in case she gets thirsty and the blonde takes a car door.
When questioned about her choice, the blonde replies:
"Well, if I get hot, I can roll down the window!"
What a winning combination?

Walter SchottkyBorn 23 Jul 1886; died 4 Mar 1976 at age 89.Swiss-born German physicist whose research in solid-state physics led to development of a number of electronic devices. He discovered the Schottky effect, an irregularity in the emission of thermions in a vacuum tube and invented the screen-grid tetrode tube (1915). The Schottky diode is a high speed diode with very little junction capacitance (also known as a "hot-carrier diode" or a "surface-barrier diode.") It uses a metal-semiconductor junction as a Schottky barrier, rather than the semiconductor-semiconductor junction of a conventional diode.« |

MAGIC SQUARE: Calculate A+B*C
The aim is to place the some numbers from the list (5, 6, 11, 29, 30, 35, 38, 59, 68, 69, 74) into the empty squares and squares marked with A, B an C. Sum of each row and column should be equal. All the numbers of the magic square must be different. Find values for A, B, and C. Solution is A+B*C.
