Fireman Test: Free Firefighter Practice Questions [2024]

The correct answer is 10 days.

To solve this problem, use the following basic formula: Work = rate*time. To start, use the information obtained from the question:

Tom's work rate: 1/20
Joan's work rate: 1/12

Indicate the number of days Tom and Joan actually worked together as "y."

Begin with the four days Tom worked on his own due to Joan's leave of absence :
Work = (1/20)*4
=> Work = 1/5 => 1/5 of the work was completed by Tom alone.

This means Tom and Joan worked together to complete the remaining 4/5 of the task:
4/5 = (1/20 + 1/12)*y
4/5 = ((3 + 5)/60)*y //60 is the common denominator of 20 and 12
4/5 = (8/60)*y //Simplify (8/60) by 4
=> 4/5 = (2/15)*y //divide both sides of the equation by (2/15)

Dividing fraction by fraction is the same as multiplying a fraction by the inverse fraction:
(4/5)/(2/15) = ((2/15)/(2/15))*y =>
(4/5)*(15/2) = ((2/15)*(15/2))*y =>
(4*15)/(5*2) = ((2*15)/(15*2))*y =>
60/10 = (30/30)*y =>
=> y = 6 days

Therefore, the total amount of days it took Tom and Joan to complete the task: 4 + 6 = 10 days.

In work rate problems, unless otherwise stated, you must assume that the rate remains the same whether the two are working together or alone.

The maximum number of people who attended a meeting, according to the table, is: 9 . The CEO and his secretary equal 2 extra people attending each meeting. Therefore, 9+2=11 people.

The leader in the car leasing industry Auto Reach has a good deal on their existing carpool in the medium-size category.

The medium size category represents 60% of their entire pool with an additional 5% of vehicles falling in both the medium and large categories.

According to the company's CFO, 5,800 medium size Auto Reach cars are on the road every day.

This popular category is expected to grow even further and reach a target of 8,000 vehicles next year.

The people behind the wheels of these cars are mostly middle-level managers from various industries. Altogether, according to the CFO, Auto Reach has a total of more than 9,500 vehicles in Europe alone.

The question deals with the benefits of using alternative fuels, described at the beginning of the passage:

(1) ’Alternative fuels…have been pitched as a way to overcome Europe's dependence on oil; no less than 94% of transport uses it, of which 84.3% is imported’.

In addition: (2) ‘alternative fuels might also be the solution to reducing the negative impact of transport on the environment’.

The first part of the sentence deals with Europe's dependency on oil and oil imports. Accordingly, distracter D is correct since reducing oil dependency is mentioned in the sentence as a benefit of using alternative fuels.

The second part of the sentence is pretty straightforward in its meaning- alternative fuels are offered as a solution to the negative impact of transport on the environment.

Therefore, distracter C is correct. Distracter A isn't correct since biofuels are alternative fuels, and the passage deals with increasing their usage.

Distracter B isn't correct because the opposite is true- alternative fuels currently cost more than oil, providing one of the reasons for low consumer demand for them.

The formula to calculate the total resistance (RT) in a circuit where N resistors are connected in parallel is:

1/RT = 1/R1 + 1/R2 + 1/R3 … + 1/RN

If we substitute the values from the figure we get:

1/RT = 1/240 + 1/40 + 1/80

The common denominator is 240:

1/RT = 1/240 + 6/240 + 3/240 = (1+6+3)/240 = 10/240 = 1/24

This is the reciprocal value for RT (1/RT), thus - RT is 24 Ω.

The correct answer is C.

The correct answer is A.

Sample of Memorization Devices for this Question Set

First let's focus on the main details that are portrayed in this image.

There are four people: three men and one woman who is mostly concealed. There is a doorman who is wearing a hat, gloves and a doorman's jacket. The second man from the left is wearing glasses, a suit, and tie. The third man is dressed more casually and is wearing a t-shirt, jacket, and pants. The only thing that can be noticed about the woman is that she is wearing glasses. Unlike the others in the photograph, we see that the doorman has a luggage cart.

Since there are not many things to remember about this image, we should pay special attention to small details which we might usually ignore. For example, notice the direction each person is facing. We see each person's left side, other than the doorman whose right side is towards the camera. We may also notice the wheels on the luggage cart and that the man on the far right has something in his left hand.
