The next section of the test also includes mathematical skills – but this time instead of visual abilities you must be able to work with different measurements and conversions from a table. Let's continue!
CAST Mathematical Usage Sample Questions
Use the information below to answer the following four questions:
Conversion table:
| 1 meter = 1,000 millimeters | 1 carreau = 1.29 bunders |
| 1 bee space = 6.5 millimeters | 1 bovate = 6 bunders |
| 1 league = 4,828 meters | 1 gal = 1,000 milligals |
| 1 bohr = 52,918 femtometers | 1 gal = 10 millimeters / square second |
| 1 bohr = 52.918 bicrons | 1 foot / square second = 30,480 milligals |
| 1 klick = 312.5 bamboos | 1 foot / square second = 12 inches / square second |
| 1 bamboo = 320 centimeters | 1 yard = 36 inches |
| 1 oxgang = 0.5 virgates | 1 inch = 2.54 centimeters |
| 1 cover = 1.349 jeribs | 1 carreau = 12.9 dekares |
| 1 acre = 160 square perches | 1 acre = 4,840 square yards |
5. 3 klicks = ? bamboos
A. 312.5
B. 625
C. 937.5
D. 960
E. None of the above
Answer:
The correct answer is C.
The conversion needs to be done as follows:
According to the table
1 klick = 312.5 bamboos
3 klick is three times 312.5 bamboos (the amount of bamboos one klick equals to).
Therefore, multiply by 3:
3 klicks = 3*312.5= 937.5 bamboos
6. 18 bunders = ? bovates
A. 1
B. 3
C. 6
D. 38.7
E. None of the above
Answer:
The correct answer is B.
The conversion needs to be done as follows:
According to the table
1 carreau = 6 bovate.
18 bunders are three times 6 bunders (and therefore, three times 1 carreau).
Therefore, multiply by 3:
18 bunders = 3*1 = 3 bovate.
7. 6 inches / square second = ? milligals
A. 0.5
B. 2
C. 15,240
D. 60,960
E. None of the above
Answer:
The correct answer is C.
While there is no direct relationship between the two measurements, both can be converted by using foot / square second:
1 foot / square second = 30,480 milligals
1 foot / square second = 12 inches / square second
Start by dividing 6 inches / square second in 12 to achieve the required multiplication factor:
6/12 = 0.5
Therefore, 6 inches / square second = 0.5*1 = 0.5 foot / square second.
Next, substitute the result (0.5) in the first equation to find how many milligals are 0.5 foot / square second:
0.5 foot / square second = 0.5*30,480 = 15,240 milligals.
Therefore, the correct answer is:
6 inches / square second = 15,240 milligals.
8. 10 centimeters = ? inches
A. 2.11
B. 3.08
C. 3.93
D. 5.24
E. None of the above
Answer:
The correct answer is C.
The conversion needs to be done as follows:
According to the table
1 inch = 2.56 centimeters
Divide 10 centimeters by 2.56 to achieve the required multiplication factor:
10/2.56 = 3.93
Therefore, 10 centimeters = 3.93*1 = 3.93 inches.
Quick Math Tip: When performing calculations (especially without a calculator), calculating the precise number may be challenging and time-consuming. If the answers are distinctly different, try to round the numbers to perform faster and easier calculations to reach an answer closest to one of the distractors.

Let’s move on to the next section – Mechanical Concepts. Basic mechanical knowledge is measured through different question types – such as simple machines, thermodynamics, and electricity. Let’s proceed.
CAST Mechanical Concepts Sample Questions
9. If the electrical switch is turned on, which light bulb will light up?
A. 1
B. 2
C. 3
Answer:
The correct answer is C.
When you turn on the electrical switch, it completes the circuit, causing bulb 3 to illuminate. However, bulb 2 is not functioning, which disrupts the circuit and prevents the electric current from reaching bulb 1. Consequently, bulb 1 will not light up.
10. Two balloons are placed side by side. Balloon A is inflated fully, while Balloon B is only half-inflated.
Which balloon has more air pressure inside? (If equal, mark C)
A. a
B. b
C. c
Answer:
The question requires a comparison of the air pressure inside two balloons: one that is fully inflated (Balloon A) and another that is half-inflated (Balloon B). The air pressure inside a balloon is typically influenced by the amount of air it holds and the space it occupies. A fully inflated balloon, like Balloon A, is stretched more tightly, causing the air molecules inside to be compressed into a smaller space than in a half-inflated balloon. This compression leads to a higher air pressure. Therefore, in this case, Balloon A, being fully inflated, would generally have a higher air pressure than Balloon B, which is only half-inflated.
The correct answer is A.
11. In which direction will the wheel spin? (If either, mark C.)
A. a
B. b
C. c
Answer:
The two wheels on the left are linked by a band, causing the top wheel to rotate counter-clockwise. The two top wheels are connected by a rod, making them rotate in the same direction. The wheel in question is attached to the top right wheel by a band, and its rotation is influenced by the top right wheel. The correct answer is B.
12. In which way is the wagon accelerating? (If either, mark C.)
A. a
B. b
C. c
Answer:
A seesaw is a first-class lever where the fulcrum is situated between the effort and the load. To balance the seesaw, the acrobat must increase the applied torque. Given that the acrobat's weight remains constant, the only way to enhance the input torque is by extending the distance from the fulcrum.
If the acrobat moves in direction B, it will shift their center of gravity further from the fulcrum, resulting in a higher torque and thus balancing the seesaw.
This is based on the principle of the second-class lever law, which states that the further the load is from the fulcrum, the greater the torque produced on that arm.
The correct answer is B.

Cast Mechanical questions require a specific set of skills and knowledge. The final section, Reading for Comprehension, may look trivial but requires verbal, grammatical, and logical abilities. Let’s continue.
CAST Reading for Comprehension Sample Questions
"In a typical woodworking shop, various mechanical tools play crucial roles in achieving precision and efficiency. The table saw, for instance, is indispensable for making straight cuts in pieces of wood.
With a high-speed rotating blade, the table saw ensures that each cut is accurate down to the millimeter. Not only can it handle large sheets of wood, but it also comes with adjustable features such as blade angle and cutting depth, allowing for customized results.
The bandsaw, on the other hand, is ideal for making curved cuts. Unlike the table saw, the bandsaw uses a continuous loop of narrow blades that runs around two or more wheels. It can make intricate shapes and is often used for tasks like cutting out patterns or creating decorative elements.
For many woodworking professionals, the bandsaw is the go-to tool for any work that involves complex geometry.
In addition to these larger tools, hand tools like chisels and planes also have their place in a woodworking shop. A chisel is used for removing wood in a controlled manner, often to create joints or hollow-out areas.
Planes are used to smooth or level surfaces, making them ideal for finishing tasks. While they may not be as fast as their electric counterparts, hand tools offer greater control and are indispensable for fine detailing work.
Safety is paramount when working with mechanical tools. Proper attire, including eye protection and earplugs, is essential. Moreover, each tool comes with its own set of safety guidelines that should be strictly followed.
For example, one should never reach over a table saw while it's in operation, and it's crucial to keep hands away from the blade of a bandsaw. Failing to follow these safety measures could result in serious injury."
