2) Last year Jose sold a painting for $2000. If he made 25% profit on the sale, how much had

he paid for the painting?

A. $1200

C. $1500

C. $1600

D. $2400

E. $2500

Jose made 25% profit, so if he bought the painting for x, he sold it for: x + 0.25x = 1.25x = 2000 ⇒x

= 2000 ÷ 1.25 = 1600.

The answer is (C).

3) In the figure below what is the value of b?

A. 30

B. 36

C. 45

D. 60

E. 72

Since vertical angles have the same measure, c = d, d = a, and b = a – b a = 2b.

Therefore, c = d = a = 2b. Also, the sum of the measures of all six angles is 3600,

so a + b + c + d + a – b + d = 2a + c + 2d = 360. Replacing c, d, and a by 2b yields

10b = 360 ⇒b =36.

The answer is (B).

4) A lacrosse team raised some money. The members used 74% of the money to buy

uniform, 18% for equipment, and the remaining $216 for a team party. How much money did

they raise?

A. 2400

B. 2450

C. 2500

D. 2600

E. 2700

SINCE 74% + 18% = 92%, THE $216 spent on the party presents the other 8 % 0f the money

raised. Then: 0.08m = 216 ⇒ m = 216 ÷ 0.08 = 2700. The answer is (E).

5) In the figure below, what is the sum of the degree measures of all of the marked angles?

A. 600

B. 620

C. 700

D. 720

E. 750

Each of the 10 marked angles is an exterior angle of the pentagon. If you take one angle at each

vertex, the sum of the degree measures of those five angles is 360; the sum of the degree

measures of the other five also is 360: 360 + 360 = 720.

The answer is (720).

6) In the figure below, ABCD is a parallelogram. What is the value of y – z?

A. 50

B. 55

C. 60

D. 65

E. 70

The sum of the degree measures of two consecutive angles of a parallelogram is

180, so 180 = (3x – 5) + (2x – 15) = 5x – 20 ⇒ 5x = 200 ⇒ x =40. Since opposite angles of a

parallelogram are equal, y = 3x – 5 = 115 and z = 2x – 15 = 65. Then y

– z = 50. The answer is (50).

7) If the length of a rectangle is 4 times its width, and if its area is 144, what is its perimeter?

A. 350

B. 360

C. 370

D. 375

E. 390

The area of Triangle CDE = 0.5(8)(15) = 60. Since the ratio of similitude for the two triangles (as

calculated in solution C15) is 2.5, the area of Triangle ABC is (2.5)2 times the area of CDE: (2.5)2 × 60 =

6.25 × 60 = 375. The answer is (375).

10) What is the perimeter of Triangle ABC?

A. 80

B. 85

C. 95

D. 100

E. 105

Solution

By the Pythagorean theorem, 82 + 152 = (CE)2 (CE)2 = 64 + 225 = 289 CE = 17. Then the perimeter of

CDE = 8 + 15 + 7 = 40. Triangles ABC and CDE are similar (each has a 900 angle, and the vertical angle

at C are congruent). The ratio of similitude is = 2.5, so the perimeter of ABC is 2.5 × 40 = 100. The

answer is (100).

14) What is the value of PS in the triangle below?

A. 5√ 2

B. 10

C. 11

D. 13

E. 12√ 2

Use the Pythagorean Theorem twice, unless you recognize the common right triangle in the figure.

Since PR = 20 and QR = 16, PQR is a 3x-4x-5x right triangle with x = 4. Then PQ = 12, and PQS is a

right angle triangle whose legs are 5 and 12. The hypotenuse, PS, therefore is 13. The answer is (D).

15) In the figure below, line k and l are parallel. what s the value of y-x?

A. 40

B. 45

C. 50

D. 55

16) In an office there was a small cash box. One day Ann took half of the money plus $1 more. Then

Dan took half of the money plus $1 more. Stan then took the remaining $11. How many dollars were

originally in the box?

A. $50

B. $45

C. $42

D. $40

E. $38

Solution

You can avoid some massy algebra by working backwards. Put back the $11 Stan took; then put back the

extra $1 that Dan took. There is now $12, which means that, when Dan took his half, he took $12. Put that

back. Now there is $24 in the box. Put back the extra $1 that Ann took. The box now has $25, so before

Ann took her half, there was $50. The answer is (A).

17) Each of the 10 players on the basketball team shot 100 free throws, and the average number of

baskets made was 75. When the highest and lowest scores were eliminated the average number of

baskets for the remaining 8 players was 79. What is the smallest number of baskets anyone could have

made?

A. 22

B. 20

D. 16

E. 14

Since the average of all 10 players was 75, the total number of baskets made was 10 × 75 = 750. Also,

since 8 of the player had an average of 79, they made a total of 8 × 79 = 632 points. The other 2

players, therefore, made 750- 632 = 118 baskets. The most baskets that the player with the highest

number could have made was 100, so the player with the lowest number had to have made at least 18.

The answer is 18.

18) Karen played a game several times. She received $5 every time she won and had to pay $2

every time she lost. If the ratio of the number of times she won to the number of times she lost was

3:2, and if she won a total of $66, how many times did she play the game?

A. 30

B. 35

C. 40

D. 45

E. 48

Karen won 3x times and lost 2x times, and thus played a total of 5x games. Since she got $5 every time

she won, she received $5(3x) = $15x. Also, since she paid $2 for each loss, she paid out $2(2x) = $4x.

Therefore, her net winning were $15x – 4x = $11x, which you are told was $66. Then, 11x = 66 ⇒ x = 6,

and so 5x = 30. The answer is (A)

19) Since 1950, when martin graduated from high school, he has gained 2 pounds every year. In

Answer B

In law, trespass can be: the criminal act of going into somebody else’s land or property without

permission of the owner or lessee; it is also a civil law tort that may be a valid cause of action to seek

judicial relief and possibly damages through a lawsuit. In some jurisdictions trespassing is an offence

or misdemeanour covered by a criminal code. In other jurisdictions, it is not considered a crime or

penal in nature, property is protected from trespass under civil law and privacy acts. In England and

Wales, despite the prevalence of notices asserting that “trespassers will be prosecuted”, unless the

trespass is aggravated in some way, it will only be a civil wrong. Although criminal and civil trespass

laws vary from jurisdiction to jurisdiction, most have the following facets in common: Property owners

and their agents (for example, security guards) may only use reasonable force to protect their

property. For example, setting booby traps on a property to hurt trespassers or shooting at

trespassers are usually strictly forbidden except in extreme circumstances. Not all persons seeking

access to property are trespassers. The law recognizes the rights of persons given express permission

to be on the property (“licensees”) and persons who have a legal right to be on the property

(“invitees”) not to be treated as trespassers. For example, a meter reader on the property to read the

meter is an invitee, as would be a travelling salesperson, or a police officer seeking to execute a

warrant.

70) A 90 Ω resistor, a coil with 30 Ω of reactance, and a capacitor with 50 Ω of reactance are in

series across a 12 V ac source. The current through the resistor is

A. 9 mA

B. 90 mA

C. 13 mA

D. 130 mA

Answer: Option D

Explanation:

V=IR

I=V/R

So.. R is nothing but Z (R=Z)

Z=sqrrt(R^2+( xl-xc)) OR (R^2+(xc-xl))

z=sqrrt_(90^2+(50-30^2)

Z=SQRRT(8100+400)

z=92.195

I=V/Z=12/92.195=0.13015=130mA.
