Mathematicians Come And Get Free Money!! by Fela40: 11:51am On Aug 18, 2017
I need a good mathematician in the house. I will post just two questions, whoever gets it first will help me run a simple project and get paid.

The purpose of this test is just to test your mathematical skills.

Please it isn't compulsory.

Question 1

John bought two clocks, which were sold for $96 each. If he had a profit of 20 percent on the sale of one of the clocks but a loss of 20 percent on the sale of the other clock, then on the sale of both clocks combined John had:

Question 2
The third-place finisher of the Allen County hot dog eating contest, in which each contestant was given an equal amount of time to eat as many hot dogs as possible, required an average of 15 seconds to consume each hot dog. How many hot dogs did the winner eat? (1) The winner consumed 24 more hot dogs than did the third-place finisher.(2) The winner consumed hot dogs at double the rate of the third-place finisher.

Re: Mathematicians Come And Get Free Money!! by huntamania(m): 12:23pm On Aug 18, 2017
Question 1 should be 192 $ since he sold the two at 96$ each regardless of loss or profit. That's how much he has.

Question 2 probably is 16 hot dogs. My flawed solution though. If x= number of hot dogs 1st place winner ate and y = number of hot dogs third place winner ate. Then x=24+y........(1) and x=2y.......(2). Solution leaded x=16 hot dogs.

Not so sure about the solution to question 2 though.

Re: Mathematicians Come And Get Free Money!! by afo7219: 12:30pm On Aug 18, 2017
Question 1 solution:
For gain 120/100×96=115.20(selling price)
For loss 80/100×96=76.8(selling price)
Therefore,
115.2-96=19.2gain
96-76.8=19.2 loss
The answer is NIL no gain no loss
Mistake
Re: Mathematicians Come And Get Free Money!! by afo7219: 12:38pm On Aug 18, 2017
Gain =96-80=16
Loss =120-96=24
Therefore overall loss in the transaction is equally to$8
Ans= $8

Correct!!!

Attempt this one as your second question

During 2015, a plant delivers an average of 2,000 cars per month. How many cars will the plant need to produce from 2016 through 2018 in order to increase its monthly average for the period from 2015 through 2018 by 200% over its 2015 average?

Explain this
Mehn, I don't like typing much with phone.
Anyway,
When u get cost price of clock A sold for $96 at 20% profit, u get $80.
When u find the cost price of the clock B sold ffor $96 at 20% loss, u get $120.
Total cost price gives u $200 and Total sellong price gives $192.
It is obvious there a loss of $8 after selling both clocks which is 4% loss.
Re: Mathematicians Come And Get Free Money!! by Nobody: 12:43pm On Aug 18, 2017
question 1

amount from first clock = 120% of $96 = $115.2
amount from second clock = 80% of $96 = $76.8

Total amount realised = $115.2 + $76.8 = $192


( no gain and no loss)


QUESTION 2

Assume the third runner up eat x hotdogs

Then The total time for the contest is 15x seconds

The winner ate (x + 24) hotdogs

The winner's rate is 1 hotdog per 7.5 seconds.

And rate = total time / number of hotdogs eatrn

Therefore, (15x)/(x + 24) = 7.5

On solving gives x = 24
The winner ate x + 24 = 48 hotdogs





These are for detailed explanations,

if not by mere logic without solving, the answers are staring at my face

2016 to 2018= 3years.
Yearly average production 2000
% increase 200%
Therefore prod = 200% of 2000= 4000
No of years is 3 so 3× 4000= 12,000 cars
Ans 12,000 cars

to get a 200% within 3 years, the production needs to double to 48,000 in 3 year.

that is a monthly average of 4,000 by 2018

Attempt this last one...

Both answers are correct, but I assume I didn't give you a unique one to answer.

Indian restaurant has 60% of spicy dishes in the menu and the rest are non-spicy. Analysis shown that in 2016 75% of the spicy dishes were profitable, but 75% of the non-spicy dishes were unprofitable. If the restaurant has a total of 40 dishes, and broke even on none of them, how many of their dishes were profitable?

200% more than 2,000 cars from 2015-2018 = 6000 cars

2015 through 2018, that is 6,000 per month, If you multiply the the company production total of 6,000*48 [Depicting the months, IE 4years]


Also in 2015, the plant produced 2,000 cars for a year, 2000*12

calc it, 6,000*48-2,000*12=

2,000*12*(3*4-1)=

2,000*12*11= 264,000

out of 40 dishes 60% = 24 were spicy
out of these 24, 75% = 18 were profitable.

similarly,
out of the 40 dishes, 40% = 16 were nonspicy
out of these 16, (100-75)% = 25% were profitable, I. e 4 were profitable

Total number of dishes profitable = 18 + 4=22

lol... This is your first attempt I guess.

This last question is for you alone.

In a group of 68 students, each student is registered for at least one of three classes - History, Math and English. Twenty-five students are registered for History, twenty-five students are registered for Math, and thirty-four students are registered for English. If only three students are registered for all three classes, how many students are registered for exactly two classes?
