Alan bought a total of 20 game cards, some of which cost $0.25 each and some of which cost $0.15 each. If Alan spent $4.20 to buy the cards, how many cards of each type did he buy?

worth 10 pts

Start by assigning X as the number of cards that cost $0.25 each and Y as the number of cards that cost $0.15. Knowing that the total number of cards equals 20, we can write the equation: X + Y = 20
Now we can say that the X cards cost: 0.25 X
And the Y cards cost: 0.15 Y
If the total cost for the cards is $4.20, we can say: 0.25 X + 0.15 Y = 4.2
Now solve the system of equations:
X + Y = 20
0.25 X + 0.15 Y = 4.2
The first equation gives Y = 20 - X. Substitute Y by 20 - X in the second equation and solve
0.25 X + 0.15 (20 - X) = 4.2
X(0.25 - 0.15) + 3 = 4.2
0.1 X = 1.2
X = 12 and Y = 20 - 12 = 8

Pump A can fill a tank of water in 5 hours. Pump B can fill the same tank in 8 hours. How long does it take the two pumps working together to fill the tank? (round your answer to the nearest minute).

worth 10 pts

We know that in an hour pump A can fill one-fifth of a tank and pump B can fill one-eighth of the same tank. So we can find out how much both pumps can fill in an hour, while working together by using the equation: 1/5 + 1/8 = 13 / 40 of a tank. Now that we know the rate, 13/40, we can find the time it takes to fill them:
(13/40) t = 1
t = 40 / 13 = 39/13 + 1/13 hours
= 3 hours and (1/13)*60 minutes
= 3 hours 5 minutes (rounded to the nearest minute)

At 10:00 a.m., Train A left the station, and an hour later Train B left the same station on a parallel track. If Train A traveled at a constant speed of 60 miles per hour and Train B at 80 miles per hour, then at what time did train B pass train A?

worth 10 pts

First, consider what the question is really asking. If the question is “at what time did Train B pass Train A.” The means the answer can be found by understanding when Train B passes Train A, which is when they have traveled the same distance. Then use the information given - the train speed and when they left the station - to calculate the distance, or: speed = distance/time.
To find distance, rearrange the equation: distance = speed(time)

Martha, Peter, and Kenneth have a total of $82 in their wallets. Martha has $10 more than Peter. Kenneth has 2 times what Martha has. How much do they have in their wallets?

worth 10 pts

Start by creating an equation that says Martha(m), Peter(p), and Kenneth(k) have $82 in total.
m + p + k = 82
Next substitute in information so that you replace all but one variable. "Martha has $10 more than Peter" --> that means we can substitute m for p + 10.
(p + 10) + p + k = 82
Then "Kenneth has 2 times what Martha has" --> k = 2 * m = 2 * (p+10)
(p + 10) + p + 2 * (p + 10) = 82
p + 10 + p + 2p + 20 = 82
4p + 30 = 82
4p = 52
p = 13

In a bag full of small balls, 1/4 of these balls are green, 1/8 are blue, 1/12 are yellow and the remaining 26 white. How many balls are blue?

worth 10 pts

First find the fraction of green, blue and yellow balls: 1/4 + 1/8 + 1/12 = 6 / 24 + 3 / 24 + 2 / 24 , common denominator = 11 / 24 , add numerators
The fraction of white balls is given by: 24 / 24 - 11 / 24 = 13 / 24 So the fraction 13 / 24 corresponds to 26 balls.
If x is the total number of balls then (13 / 24) of x = 26 balls or (13 / 24) × x = 26
x = 26 × (24 / 13) = 48 , total number of balls
The fraction of blue balls is 1 / 8 of x. The number of blue balls is given by (1 / 8) of 48 = 6 balls.

A car travels from point A to point B at 40 mph then returns, using the same road, from point B to point A at 60 mph. What is the average speed for the round trip?

worth 10 pts

Find this answer by calculating total distance divided by total time.
If x is the distance from A to B, then the total distance is equal to 2x (away and return). The total T time is equal to time t1 = x / 40 from A to B (away) plus t2 = x / 60 from B to A (return). Hence
T = x / 40 + x / 60 = 100 x / 2400 = x / 24
The average speed is given by: 2x / (x/24) = 48 mph

At 11 a.m., Joe started driving at 50 miles per hour. Fifteen minutes later, Beth started driving along the same highway in the same direction as Joe at 65 miles per hour. At what time will Beth catch up with Joe?

worth 10 pts

If “t” represents the number of hours, from 11 am, when Beth catches up with Joe. The time that Beth will have to drive to catch up with Joe, then, is t - ¼.
Beth starts a quarter of an hour late. When Beth catches up with Joe, they would have traveled the same distance. So:
50 t = 65 (t - 1/4)
Then solve for t
50t = 65t - 65/4
t = 65/60 = 1.083 hours = 1 hour and 5 minutes
Beth will catch up with Joe at
11 am + 1 hour , 5 minutes = 12:05 pm

Can you find the area of a trapezoid only by knowing that the parallel sides are 12 and 23 centimeters long, respectively?

worth 10 pts

The area A of a trapezoid is given by
A = (1/2) height *(base1 + base2)
The two bases are given as 12 and 23 cm, however, the height is not given and therefore there is not enough information to find the area of the trapezoid.

A rectangular garden in Mrs Jewett’s house has a length of 100 meters and a width of 50 meters. She plans to build a square swimming pool inside the garden. Find the length of one side of the swimming pool if the remaining area (not occupied by the pool) is equal to one half the area of the rectangular garden.

worth 10 pts

Make “x” represent the side of the swimming pool. If the area not covered by the swimming pool is half the rectangular garden, then the other half is covered by the swimming pool whose area is x2. So:
x2 = (1/2) 100*50 = 2500
Solve for x
x = 50 meters , side of the swimming pool

About This Quiz

Quiz Updated: July 1, 2019

What a brave soul, taking on this math test. It is certainly not for the faint of heart. Fifty challenging questions that are sure to give you flashbacks to high school math exams. If you know a little basic math - and a little algebra and geometry - you should do just fine.

Word problems are nothing new. Math maniacs were challengings themselves with words and numbers as far back as Babylonian times. Instead of trains traveling from point A to point B, though, Babylonians measured canals and weighed stones. Their word problems were practical. You knew why you were learning math, that’s for sure.

Ancient Egyptian teachers teased students with multiplication quizzes and word problems that read something like “There are seven houses, each with seven cats, and each catches seven mice …” Makes your head spin just reading it, doesn’t it?

Word problems confounded students during the Renaissance and through the American Revolution. Plenty of literary giants and everyday comedians have made fun of confusing math practice tests that read more like fantasy novel than a math test.

Modern satirists, like the writers on 'The Simpsons', have produced some famous word problems, and some have found their way into 'Saturday Night Live' sketches as well. Truth told, we all love to hate word problems. But they help us to better understand mathematical concepts and tease out the answers to common problems.

In case you don’t think you’re using word problems in your everyday life, just consider every time you have to leave a tip. How easy is it to express that moment as “My server brought me my meal on time and in good order. Since she did so well, I decided to tip her 20 percent of my bill. When the bill came, I owed $45. How much was my tip?”

So there you go. Word problems are serious business. And so is this math test. Are you ready? Let’s see how you do!

**Tags:** addition, division, drills, math, mathematics, multiplication, subtraction, word problems
