1. What comes next in this sequence?
31 41 59 26 53 58 9?

**This is really just pi: 3.1415926535897…**

2. What's the missing number?

382
13 661

429 15 780

551 11 821

158 14 716

933 ? 258

**15. Each two digit middle number is the sum of the three digits of the two numbers on either side of the middle.**

3. I have some rare coins. Each coin either has a value of 12
silver pieces or 7 gold pieces. 40 of my coins are going to be exchanged for silver and gold coins. I just found out that
there are only 119 gold coins left. How many silver coins should I expect to receive with those 119 gold coins?

**276 silver coins. If you were to exchange for gold only, it would require 40 x 7 or 280 gold coins. But there are only 119, leaving 161 gold coins short. The value of silver coins to gold coins is in the ratio of 12 to 7. The math is 12/7 = x/161, then 7x = 1932; to x = 276.**

4. There are 100 people applying for a job that requires both a
science and business background. 12 have no experience in either field. 64 have a science background and 80 of the applicants have a business
background. How many of the applicants have a background in science and business?

**56. Since 12 have no background in either field, we have 88 applicants who have some experience in one area or the other. Of 88, 64 of them have a science background, which means 24 of this group don't have a science background (88 - 64 = 24). 80 people have a business background, which means 8 out of the 88 don't have a business background. 28 + 8 = 32 people who have no background in either; so 88 - 32 = 56 people who have both science and math backgrounds.**

5. What number comes next in this
sequence?

20
26 21 28
24 32 29 38 36 ?

A) 30 B) 42
C) 46 D) 49

**The answer is C) 46. Here is how the sequence proceeds: Add 6, take away 5, add 7, take away 4, add 8, take away 3, add 9, take away 2, add 10, which makes it 46.**

6. Suppose all the counting numbers were arranged in rows and
columns as shown below:

A B C D E F

1 2
3 4 5
6

7 8
9 10 11 12

13 14
15 16 17 18

19 20
21 22 23 24

25 26
__ __ __ __

Under what letter will the number 2000
appear?

**It will appear under "B", in the 333rd row.**

7. A special group of engineers from the Army has been selected
to work on a new project. There are 120 lieutenants, 53 captains, and 37 majors and a group of colonels that comprises 3/10 of the total group. How many
engineers in total are working on this project?

**The answer is 300. If 3/10 are colonels, then 7/10 are lieutenants, captains and majors. 120 + 53 + 37 = 210. 7/10x = 210, then 10/7 x 7/10x = 210 x 10/7, then X = 2100/7, then X = 300 engineers.**

8. The product of two numbers is 161.
The difference between the two is 16. What are the two numbers?

**The numbers are 7 and 23.**

9. What is the probability of drawing three clubs in a row from a
normal deck of 52 cards? The cards are not returned to the deck once they've been chosen.

A) a little more than 1%

B) 1 out of 4

C) 1 out of 10

D) 1 out of 13

**A) a little more than 1%. The math is as follows: 13/52 x 12/51 x 11/50 = 11/850 = 1.29%.**
