A 10%

B 20%

C 30%

D 40%

E 50%

The best answer is C

In this question you’ll need to use the data from both graphs

Sum up the bars of both the ovens and the televisions They both sum up to 58 Sum up the bars of all the appliances in all the categories, they will sum up to

approximately 200 or so Now, 58 out of 200 are a little under 30% and therefore answer C is the best answer

2 If X represents the number of DVD’s that were made in U.S and were sold during December, how many Televisions that were made in the China sold that month?

A X

B 1.5X

C 2X

D X/2

E 6X

The best answer is E

According to the bar chart, X represents approximately 5 DVD’s that were sold

Go to the T.V category, you can see that approximately 30 televisions that were made

in china were sold in December and therefore the answer is 30/5 = 6X

3 For the individual category in which the second greatest number of appliances made in the U.S were sold, the number of appliances made in the U.S exceeded the number of appliances made in China by how much approximately?

A 0

B 1

C 2

D 3

E 4

The best answer is C

First identify the category in which the number of appliances made the U.S is the second in size, which would have to be the “ovens” category In that category 14 (U.S) ovens were sold and (China) 12 ovens were sold The difference is 2 ovens and therefore the answer is C

4 According to the graph, to which of the following categories was the ratio between appliances that were made in China to appliances that were made in the U.S the greatest?

A Refrigerators

B Mixers

C Speakers

D Televisions

E DVD’s

The best answer is

Check the approximate ratio in each of the options:

A 6 to 6, which is 1

B 11 to 3, which is 3 and two thirds

C 15 to 28, not relevant since B is greater

D 30 to 2, which is 15- we got a winner

E 13 to 5, not relevant since D is better

And therefore the greatest ratio will be in the Televisions categories

Revenue and profit distribution for Organic and Non-organic materials

Over the years 1991 to 1995

The 3 first graphs should be attached here

1 Approximately how much did the total revenues increase from 1991 to 1995?

A $4,400

B $5,000

C $6,500

D $8,000

E $11,200

The best answer is C

First familiarize your self with the graphs

The question is about the graph of the revenues, look at the difference between the top value of the column in 1991 and 1995 You can see that the difference between the years is approximately (21,500 – 15,000 = 6,500) and thus the answer is C

2 In the year which profits from Organic materials decreased over the previous year, the revenues from Non-organic materials were approximately

A $12,500

B $10,000

C $7,500

D $6,200

E $4,000

The best answer is A

Refer to both bar graphs Look for the year in which the Organic bar is lower than its previous year, the only year is 1995 Then go to the other bar graph and look again in

the year 1995, the revenues from Non-organic materials are (15,000 – 2,500 = 12,500) and thus the answer is A

3 In the year which profits from Organic materials are the lowest, what percent approximately of the total revenues belong to the Organic materials?

A 22%

B 28%

C 35%

D 45%

E 65%

The best answer is C

Refer to both bar graphs From the profit graph, we can learn that the question is asking about the revenues of the year 1993 In that year, revenues from Organic materials present approximately $8,000 and the total revenues are approximately

$22,000 In percent terms the answer is (8/22 = approximately 36 percent) and so the best answer is C

4 In 1994, total profits represented approximately what percent of Geeweez’s total revenues?

A 25%

B 30%

C 40%

D 50%

E 65%

The best answer is C

Refer to both bar graphs From the profit graph, we can conclude that the total profits for 1994 are approximately $9,500 From the revenue graph, we can conclude that the total revenues are approx $24,000

(9,500 / 24,000) in percent terms is approx 40% and thus C is the answer

5 The profits on Non-organic materials in 1992 are approximately what percent of the total revenues in 1994?

A 15%

B 25%

C 35%

D 45%

E 55%

The best answer is B

Refer to both bar graphs Look in the year 1992 in the profit graph, the profits from the upper bar column, which belongs to the Non-organic materials is approx (10,000 – 4,000 = 6,000) In the year 1994, the total revenues are approx $24,000 and thus the answer in percent terms is (6/24 = 0.25) 25%

6 For the first year in which Non-organic materials revenues surpassed $16,000, total profits were approximately

A $3,200

B $6,500

C $8,000

D $9,500

E $10,500

The best answer is A

Look at the revenues graph, start in 1991 and go through the years until you find one that the revenues from Non-organic materials is over $16,000, the first possible year

is 1994 Now go to the second graph and see how much profits were made that year, the answer is approx $3,200

7 For the last year in which profits from Organic materials were under $2,000, approximately what were the total revenues in the previous year?

A $15,000

B $17,500

C $22,000

D $24,000

E $21,000

The best answer is D

This is a tricky question, pay attention

We were asked about the last year so start from 1995 and move down the years In

1995 the profits from Organic materials were under $2,000 and so the question is asking the total revenues in the previous year, thus in 1994

The answer is approx $24,000

8 In 1994, what were the Non-organic revenues, which belong to the Metal group?

A $8,500

B $9,600

C $10,800

D $12,000

E $13,200

The best answer is C

First look at the revenue bar graph, the total Non-organic revenues are $18,000 Now move to the pie graph, you can see that the metal group is 60% of the total and therefore 60% of 18,000 are the correct answer (0.6 x 18,000 = 10,800)

9 Of the Non-organic revenues in 1994, how much approximately were not made from metal or glass?

A $2,150

B $3,200

C $4,100

D $5,000

E $5,500

The best answer is A

First look at the revenue bar graph, the total Non-organic revenues are $18,000

Now move to the pie graph, you can see that the metal group is 60% of the total and the glass group is 28% and therefore 12% of 18,000 are left, which are also the clay group (0.12 x 18,000 = 2,160) The closest answer is A

10 What percent approximately are the revenues of the Non-organic Metal materials

in 1994 relative to the total profits in the years 1994 and 1995?

A 25%

B 35%

C 45%

D 55%

E 65%

The best answer is D

First look at the revenue bar graph, the total Non-organic revenues are $18,000 Now move to the pie graph, you can see that the metal group is 60% of the total and therefore 60% of 18,000 are $10,800

Now go to the profits graph, the total profits in 1994 and 1995 are approx $19,000

In percent terms, 10.8/19 is approximately 55% and thus answer D is the best

1 The team that made the finals played 50% more games Which of the following teams made it to the finals?

A Team A

B Team B

C Team D

D Team E

E Answers B and C

The best answer is E

We are given a piece of substantial information, a team that made it to the finals played 50% more games than a team that didn’t

We can see from the graph that some teams played a total of 40 games and the others played a total of 60 games and therefore those teams made it to the finals

The answer is E, meaning that teams B and D made it to the finals

2 For the team with the least number of loses, what percent approximately are the tied games of the total number of games?

A 20%

B 33%

C 40%

D 45%

E 50%

The best answer is B

The team with the least amount of loses is Team B, you can see that by comparing the sizes of the uni-colored bars for all teams The number of tied games is 20 and the total number of games is 60 and therefore the percent is 20/60, which is

approximately 33%

3 For the team with the median amount of tied games, won games represented

approximately what percent of that team’s total games for that year?

A 24%

B 37%

C 44%

D 53%

E 61%

The best answer is D

Look through all the teams for the median number of tied games The median can easily be found: There are 5 teams and therefore the median number would be the one, which has 2 smaller and 2 bigger tie games than his, the right team is D

Team D won 32 games, which is approximately a little over 50% and therefore the best answer is D

4 If Team E won 15 games in the year 2000, Team’s E winnings increased by what percent from 1999 to 2000?

A 50%

B 100%

C 200%

D 250%

E 300%

The best answer is C

Team E won 5 games in 1999

15 are 300% of 5 and therefore there was an increase in 200% in the number of games won from the year 1999 to 2000

5 If each team receives 3 points for winning a game, 1 point per tie game and 0 points per lose, which team collected the greatest amount of points in the year 1999?

A Team A

B Team B

C Team C

D Team D

E Team E

The best answer is B

At first glance, the answer is either B or D since both teams won a lot of games compared to all the other teams If you were more specific, you will see that team B tied more games than team D and therefore collected a greater amount of points

The following table describes a certain family with five kids, on Christmas; each kid receives money from each of the older family members Each family member spends

a certain amount of money on gifts per child; the numbers in the middle of the table describes the distribution For example, dad gave 15% of his gift money to kid B

1 Which family member gave Kid D one fifth of his Christmas money?

A Mom

B Dad

C Grandmother

D Grandfather

E None of the answers are correct

The best answer is E

The numbers in the middle of the table represent the percent of the total money that each family member spent on a certain kid Don’t be mistaken, mom spent 20% of her gift money on kid D, yet Grandfather's 15% could be more because we don’t know which family member spent more money on gifts

2 Which family member spent a quarter of his gift money on kid B and kid D?

A Dad

B Mom

C Grandmother

D Grandfather

E Uncle Bob

The best answer is D

You are looking for a family member that spent 25% on both B and D

If you add the percentages in columns B and D, you will know what percent each

family member spent on those kids The sum of grandfather adds up to 25% and

therefore he is the only family member who spent a quarter of his money on kid B and

D
