### If Sally can paint a house in 4 hours, and John can paint the same house in 6 hours, how long will it take for both of them to paint the house together?

• A.

2 hours and 24 minutes

• B.

3 hours and 12 minutes

• C.

2 hours and 45 minutes

• D.

1 hour and 5 minutes

A. 2 hours and 24 minutes
Explanation
Sally can paint 1/4 of a house in 1 hour, while John can paint 1/6 of a house in 1 hour. To find out how long it will take them to paint the house together, we need to add their rates of painting. The combined rate is 1/4 + 1/6 = 5/12. To find the time it will take to paint the whole house, we take the reciprocal of the combined rate, which is 12/5. Converting this to hours and minutes, we get 2 hours and 24 minutes.

### The sales price of a car is \$12,590, which is 20% off the original price. What is the original price?

• A.

\$14,310.40

• B.

\$14,990.90

• C.

\$15,290.70

• D.

\$15,737.50

D. \$15,737.50
Explanation
To find the original price, we need to determine the price before the 20% discount. We can set up an equation: original price - (20% of original price) = sales price. Let x represent the original price. The equation becomes x - 0.2x = 12,590. Simplifying, we have 0.8x = 12,590. Dividing both sides by 0.8, we find that x = 15,737.50. Therefore, the original price of the car is \$15,737.50.

### If Leah is 6 years older than Sue, and John is 5 years older than Leah, and the total of their ages is 41. Then how old is Sue?

• A.

8

• B.

10

• C.

14

• D.

19

A. 8
Explanation
Since Leah is 6 years older than Sue, and John is 5 years older than Leah, we can deduce that John is 11 years older than Sue. If we let Sue's age be x, then Leah's age would be x + 6, and John's age would be x + 6 + 5 = x + 11. The sum of their ages is given as 41, so we can write the equation: x + (x + 6) + (x + 11) = 41. Simplifying the equation, we get 3x + 17 = 41. Solving for x, we find that x = 8, which means Sue is 8 years old.

### Jim is able to sell a hand-carved statue for \$670 which was a 35% profit over his cost. How much did the statue originally cost him?

• A.

\$496.30

• B.

\$512.40

• C.

\$555.40

• D.

\$574.90

A. \$496.30
Explanation
To find the original cost of the statue, we need to divide the selling price by 1 plus the profit percentage. In this case, the profit percentage is 35%, so we divide \$670 by 1.35 (1 + 0.35). This gives us \$496.30, which is the original cost of the statue.

### Grace has 16 jellybeans in her pocket. She has 8 red ones, 4 green ones, and 4 blue ones. What is the minimum number of jellybeans she must take out of her pocket to ensure that she has one of each color?

• A.

4

• B.

8

• C.

12

• D.

13

D. 13
Explanation
To ensure that Grace has one jellybean of each color, she needs to take out the maximum number of jellybeans of the same color, which is 8 (red). Then, she needs to take out one more jellybean of each remaining color, which is 4 (green) and 4 (blue). Therefore, the minimum number of jellybeans she must take out is 8 + 1 + 1 + 1 = 11. However, since the question asks for the minimum number of jellybeans to ensure that she has one of each color, she must take out one additional jellybean, making it a total of 11 + 1 = 12.

### If r = 5 z then 15 z = 3 y, then r =

• A.

Y

• B.

2y

• C.

5y

• D.

10y

A. Y
Explanation
If r = 5z and 15z = 3y, we can substitute the value of r in the second equation. Since r = 5z, we can rewrite the second equation as 15z = 3y. Dividing both sides of the equation by 3, we get 5z = y. Therefore, the value of r is y.

### Lee worked 22 hours this week and made \$132. If she works 15 hours next week at the same pay rate, how much will she make?

• A.

\$57

• B.

\$90

• C.

\$104

• D.

\$112

B. \$90
Explanation
If Lee worked 22 hours and made \$132, we can find her hourly rate by dividing her total earnings by the number of hours worked. In this case, her hourly rate is \$132/22 = \$6. Therefore, if she works 15 hours next week at the same pay rate, she will make 15 * \$6 = \$90.

### You purchase a car making a down payment of \$3,000 and 6 monthly payments of \$225. How much have you paid so far for the car?

• A.

\$3225

• B.

\$4350

• C.

\$5375

• D.

\$6550

B. \$4350
Explanation
The down payment of \$3,000 is the initial amount paid for the car. In addition to that, there are 6 monthly payments of \$225 each, which totals to \$1,350 (\$225 x 6). To find the total amount paid so far, we add the down payment and the monthly payments: \$3,000 + \$1,350 = \$4,350. Therefore, the correct answer is \$4350.

### If y = 3, then y3(y3-y)=

• A.

300

• B.

459

• C.

648

• D.

999

C. 648
Explanation
The expression y3(y3-y) can be simplified by substituting the value of y as 3. So, the expression becomes 33(33-3), which simplifies further to 27(30). Multiplying 27 by 30 gives us the result of 810. Therefore, the correct answer is 810.

### Your supervisor instructs you to purchase 240 pens and 6 staplers for the nurse's station. Pens are purchased in sets of 6 for \$2.35 per pack. Staplers are sold in sets of 2 for 12.95. How much will purchase these products cost?

• A.

\$132.85

• B.

\$145.75

• C.

\$162.90

• D.

\$225.25

A. \$132.85
Explanation
To calculate the cost of purchasing the pens, divide the total number of pens needed (240) by the number of pens in each set (6). This gives us 40 sets of pens. Each set of pens costs \$2.35, so multiplying 40 by \$2.35 gives us \$94. To calculate the cost of purchasing the staplers, divide the total number of staplers needed (6) by the number of staplers in each set (2). This gives us 3 sets of staplers. Each set of staplers costs \$12.95, so multiplying 3 by \$12.95 gives us \$38.85. Adding the cost of the pens and the staplers together gives us \$94 + \$38.85 = \$132.85. Therefore, the correct answer is \$132.85.

### Questions 16-19. In the sixteenth century, an age of great marine and terrestrial exploration, Ferdinand Magellan led the first expedition to sail around the world. As a young Portuguese noble, he served the king of Portugal, but he became involved in the quagmire of political intrigue at court and lost the king's favor. After he was dismissed from service to the king of Portugal, he offered to serve the future Emperor Charles V of Spain. A papal decree of 1493 had assigned all land in the New World west of 50 degrees W longitude to Spain and all the land east of that line to Portugal. Magellan offered to prove that the East Indies fell under Spanish authority. On September 20, 1519, Magellan set sail from Spain with five ships. More than a year later, one of these ships was exploring the topography of South America in search of a water route across the continent. This ship sank, but the remaining four ships searched along the southern peninsula of South America. Finally they found the passage they sought near a latitude of 50 degrees S. Magellan named this passage the Strait of All Saints, but today we know it as the Strait of Magellan. One ship deserted while in this passage and returned to Spain, so fewer sailors were privileged to gaze at that first panorama of the Pacific Ocean. Those who remained crossed the meridian we now call the International Date Line in the early spring of 1521 after ninety-eight days on the Pacific Ocean. During those long days at sea, many of Magellan's men died of starvation and disease. Later Magellan became involved in an insular conflict in the Philippines and was killed in a tribal battle. Only one ship and seventeen sailors under the command of the Basque navigator Elcano survived to complete the westward journey to Spain and thus prove once and for all that the world is round, with no precipice at the edge. The sixteenth century was an age of great ___exploration

• A.

Cosmic

• B.

• D.

Common man

B. Land
Explanation
During the sixteenth century, there was significant exploration of both marine and terrestrial (land) areas. This period saw expeditions and voyages to discover new lands and establish trade routes. Ferdinand Magellan, mentioned in the passage, led the first expedition to sail around the world, which involved exploring both land and sea. Therefore, the correct answer is "Land" as it aligns with the historical context provided in the passage.

• B.

Transformer

• C.

Capacitor

• D.

Series circut

B. Transformer
Explanation
A transformer is a device that is used to change the voltage and amperage of an electric current. It consists of two coils, known as the primary and secondary coils, which are wound around a common iron core. When an alternating current passes through the primary coil, it creates a changing magnetic field. This changing magnetic field induces a voltage in the secondary coil, which can be either higher or lower than the voltage in the primary coil, depending on the number of turns in each coil. Therefore, a transformer can step up or step down the voltage and amperage of a current.

### When referring to an electronicÂ circuit, AC stands for

• A.

Actuator Circulator

• B.

Alternating Current

• C.

Anterior Condition

• D.

Air Conditioner

B. Alternating Current
Explanation
AC stands for Alternating Current in the context of an electronic circuit. Alternating Current refers to the flow of electric charge that periodically reverses its direction. This type of current is commonly used in electrical power systems as it allows for efficient transmission of electricity over long distances. Unlike Direct Current (DC), which flows in only one direction, AC constantly changes its polarity, resulting in a sinusoidal waveform. This alternating nature of the current enables it to power various electronic devices and appliances efficiently.

### Which of the following is not a form of precipitation?

• A.

Rain

• B.

Sleet

• C.

Fog

• D.

Hail

C. Fog
Explanation
Fog is not a form of precipitation because it is composed of tiny water droplets suspended in the air, rather than falling from the atmosphere like rain, sleet, or hail. Precipitation occurs when water vapor condenses into liquid or solid form and falls to the ground due to gravity. Fog, on the other hand, forms when warm air cools and reaches its dew point, causing water vapor to condense into tiny droplets near the ground.
