Elevator Industry Aptitude Test (EIAT) Practice Question

There are three sections in the EIAT test - Math, Verbal Reasoning, and Mechanical Aptitude. Here is a free Elevator Industry Aptitude Test example question you can try.

Elevator Mechanical Cogwheels Question

2. In which direction does the woman have to turn the handle so that the cylinder will rotate in the direction shown in the diagram below?

A. Counter-clockwise.

B. Clockwise.

C. The cylinder will not rotate.

D. Either way. 


The correct answer is 2. 

According to the diagram, the woman wishes to turn the cylinder in a counter clockwise direction. We can see that one cogwheel connects with the same axis of rotation as the cylinder; therefore, it will turn in the same direction as the cylinder.

In order for the upper cogwheel to turn in a counter clockwise direction, the lower cogwheel must turn in a clockwise direction. Since the lower cogwheel is attached to the handle that the woman has to turn, she must therefore turn it in a clockwise direction.

Carpentry Pre-Apprenticeship Practice Test Question

The Carpenter Apprenticeship test includes Arithmetic Computations and Reasoning, Applied Mathematics and Science, Mechanical Comprehension, Spatial Reasoning, and Reading Comprehension. Here is a free Carpenter Apprenticeship example question you can try.

Carpenter Reading Comprehension Question

4. Although Britain would not use African troops in Europe, as this would "undermine the dignity of the white man", to Britain’s horror and disapproval, France used some 160,000 Africans from its west African colonies in Europe, with another 65,000 used elsewhere. Britain used some 50,000 African troops and about one million ‘carriers’ in the African campaigns and some 1,000 were used in Mesopotamia. The death rates were high: in the east African campaigns, over 11,000 African soldiers and around 100,000 carriers died; some 22,000 were wounded and/or missing-in-action.

As opposed to Britain, where did France use African soldiers?

A. in Europe.

B. in Mesopotamia.

C. in the African campaigns.

D. in India.



The correct answer is (A).

According to the passage, "Although Britain would not use African troops in Europe… France sent some 160,000 Africans from its West African colonies to Europe" – so Britain did not employ African troops in Europe, while France did. The passage also states that Britain did use African soldiers in Africa and Mesopotamia, so answers (B) and (C) are incorrect. As for answer (D), India is not mentioned in the passage at all.

Ironworker Geometry Question

5. Please choose the correct answer. If none of the options is the correct answer please choose answer choice e, "N".

If Antimony melts at 1,625.67 degrees Rankine, at what Celsius temperature will it melt?

A. 903.15.

B. 751.4.

C. 630.

D. 3,417.876.

E. N


The correct answer is (C) - 630

The formula for calculating degrees Rankine is:
Degrees Rankine = (degrees Celsius + 273.15) x 1.8

Isolate the 'Celsius degrees' in the formula:
1. Divide both sides of the equation by 1.8
Degrees Rankine/1.8 = (degrees Celsius + 273.15) x 1.8/1.8 
Degrees Rankine/1.8 = degrees Celsius + 273.15
2. Subtract 273.15 from both sides of the equation:
(Degrees Rankine/1.8) - 273.15 = degrees Celsius + 273.15 - 273.15
(Degrees Rankine/1.8) - 273.15 = degrees Celsius
Degrees Celsius = (Degrees Rankine/1.8) - 273.15

Insert the given data:
Antimony's melting point = 1,625.67 degrees Rankine.
Degrees Celsius = (1,625.67/1.8) - 273.15 = 903.15 - 273.15 = 630

Solving tip: When dividing two decimals might be easier to turn them into integers by multiplying both the nominator and denominator by a shared multiplication of 10 (i.e. 10, 100, 1000 etc.), e.g.:

Use long division:

=> 903 + a remainder of 27 = 903 + 27/180 = 903 + 3/20  

In order to convert the fraction 3/20 into a decimal we can manipulate the fraction to our advantage, using familiar fractions.
The first, easiest possibility is expanding the fraction, turning it to a fraction of a 10's denominator (i.e. 10,100,1,000 etc.). In this case, multiply both the nominator and denominator of 3/20 by 5:
5*3/5*20 = 15/100 = 0.15
903 + 3/20 = 903 + 0.15 = 903.15

A second possibility is manipulating a fraction, by using fractions whose decimal equivalents are well known and are easy to use e.g.: 1/2 (0.5), 1/4 (0.25) etc.

3/20 = (1*3)/(2*10) = (1/2)*(3/10) = 0.5*0.3 = 0.15
903 + 3/20 = 903 + 0.15 = 903.15

Now, we can return to our formula and compute the final answer:
Degrees Celsius = 903.15 - 273.15 = 630

Heavy Equipment Mechanical Question


8. Danny received a bunch of colorful helium balloons for his birthday. One of the balloons was not attached properly and flew away.

Assuming the temperature remains constant, what will be the volume of the balloon at a very high altitude? 

A. Smaller.

B. Bigger.

C. Unchanged.

D. Cannot say. 


In order to answer this question one should know the Ideal Gas Law:


where P =pressure, V = volume, n = number of moles of gas (amount of gas), R = Gas constant, T = temperature.

Since we know the temperature is constant, the right side of the equation will also be constant (providing the amount of gas in the balloon remains constant, meaning: PV = Const, at all times.

As the balloon raises atmospheric pressure decreases since the amount of air above it the balloon is reduced (similar to hydrostatic pressure).

If the pressure decreases (as the balloon raises) then the volume must increase in order for P*V to remain constant.

Boilermaker Math Word Problem Question

9. A client brings a check for $563.04. He wants to deposit $326 into his checking account, get $40 in cash and deposit the rest into a savings account. How much will he deposit into this savings account?

A. 197.04$

B. 204.04$

C. 297.04$

D. 299.04$ 


The correct answer is A.

First, let's calculate how much money the client wants in his checking account and in cash:
Checking+cash= 326+40 = 366.

Now, we subtract this number from the total amount of money – the sum of the check:
563.04-366 = 197.04.

Alternative explanation: If we only subtract $326 (the deposit) from $563.04 (the check/total), we get $237.04 – even before subtracting the amount of cash, we can eliminate answers C and D, as they are too much. Next we would subtract $40 from $237.04, but notice that since 40 is a larger number than 37, we know that the result will be smaller than 200, and so we can also eliminate answer choice B and choose answer A, the correct answer.

Welder Apprenticeship Number Series Question

11. The numbers in the figures below have the same mathematical relationship to one another.

What number should replace the question mark in the figure below?

A. 0.

B. -2.

C. -6.

D. 4.



The correct answer is (B).

All the circles below exhibit the same numerical relationship - they share the following pattern:

(left-cell) - (right-cell) = 4;

Left circle: 4 (top-left) – 0 (top-right) = 4; 5 (bottom-left) – 1 (bottom-right) = 4
Middle circle: 8 (Top left) - 4 (top right) = 4; 6 (bottom left) - 2 (bottom right) = 4
Right circle: 2 (Top left) - (-2) (top right) = 2 + 2 = 4; 0 (bottom left) - (-4) (bottom right) = 0 + 4 = 4

*Notice! Two minuses cancel each other, and turn into a plus sign:
- (- number) = + number

The circle in question: 6 (Top left) - 2 (top right) = 4; 2 (bottom left) - ? (bottom right) = 4
2 - ? = 4    //Gather all numbers on one side and the ? sign on the other side
-? = 4 - 2
-? = 2      //Eliminate the minus sign from the (?)  sign, (since you are asked for the value of ?), by multiplying both sides of the equation by (-1)
(-1)*(-?) = (-1)*2
? = -2
