A carpenter makes 3 bunk beds every day. A military school needs to organize a place to sleep for 143 soldiers. If there are 5 carpenters working on the job, how many whole days in advance should they receive the order and start working in order to finish the right number of beds assuming that each bunk-bed is used by two soldiers?

  1. 3.
  2. 4.
  3. 5.
  4. 6.
  5. 7.

Answer(s): C

Explanation:

143 soldiers is not an even number so we need at least 72 beds (one will sleep alone).
The carpenters together can complete 15 beds a day. 72/15 is between 4 and 5 so they will need 5 days notice in order to complete the job on time.

In the following sequence: [x, y, z, 5, 7, 16, 28] each number is equal to the sum of the three numbers preceding it. What is x+y?

  1. -5
  2. -1
  3. 1
  4. 5
  5. 6

Answer(s): C

Explanation:

First find z: z+5+7=16, therefore, z=4. Now, y+4+5=7 making y=(-2). Now we can find x: x+(-2)+4=5, so, x=3. Hence, x+y=3+(-2)=1.
