5. Which will carry more water – a pipe 20” in diameter or two 12” pipes? Assuming both pipes are the same length and are carrying water to their maximum, which will be able to deliver more water per unit of time to a swimming pool?

Answer:
The 20” pipe will carry more water.  One way to reason this is to look at the area of the hole (circle) the water will exit.  The area of a circle is pi x rē, where r is the radius.  Since the radius of the 20” pipe is 10” and the radius of the two 12” pipes is 6” each, you have 10” squared for 100 and 6” squared twice for 36 + 36 = 72.  Of course, pi is disregarded for comparison purposes because it remains the same for both pipes.


6.
What capital letter comes next? R, S or T ?
 A, B, D, O, P, Q,  ?
Answer:
R. These are the capital letters that are created with at least one closed loop in their make-up.
