Equilibrium point (10,5) will give you value of k from Demand curve given by P=k/Q or k=PQ=10*5=50. So we just require a and b, which are used only in supplu curve, so statement 2 is of no help. equilibrium point(10,5) substituted in supply curve equation will give one equation in a and b. We require another equation which is given by point (8,1) in statement 1. Thus statement I is sufficient...A

Both restaurants in downtown Rosemond-Sam’s Diner and the Main Street Cafe-offer a lunch special consisting of a sandwich, a dessert, and a drink for a set price. Which restaurant offers customers more choices for the lunch special? (1) The Main Street Café offers twice as many sandwich choices as Sam’s Diner. (2) Sam’s Diner has 2 more drink choices and 2 more dessert choices than the Main Street Café.

Combined..Main street has ways = 2a*x*y and Sam’s = a*(x+2)(y+2)....From this we cannot say which will be larger. say x and y are 2, then M=8a and S=16a..S>M. But say x=y=10, then M=200a while S=144a...M>S.....Answer is E

For the 3 payments you just do ($2000 + $1000 + $500) per balloon. And there 10 ballons so times it by 10 giving you $35k. So 40k - 35K is 5k

Quote

Private

same for 4 payments, you do ($2000 + $1000 + $500 + $250), multiplied by 10, giving you $37.5K. 40k - 37.5k is 2.5K

In the first sentence we need a synonym of irrespection, that is "whether or not". Similarly the second statement can be derived from the first statement of the question, so they can end in a draw only if paul jr has not played.

OFFICIAL TEST QUESTION

Quote

Private

by median method I’m getting two 50s and two 33.33s. how do I know which one wud be one. by mode metjod they are 1 and 2.

Quote

Private

Delete

It’s nothing but the basic application of Median and Mode:
Using Mode Method:
Look for the highest number (frequency) in each Rank Column from 1 through 3
Rank 1- Performer A (with 51 votes)
Rank 2- Performer C (with 95 votes)
Rank 3- Performer B (with 72 votes)
Now, using Median Method:
Each column adds up to 100 votes. So, rank assignment would be based on the answer of 50th and 51st terms
Rank 1- Performer A
Rank 2- Performer C
Rank 3- Performer B
Since we arrive at the same answer using both the methods, therefore, “Same” column of the question stem must be selected for all the ranks.

Hi, can anyone please explain this question

Quote

Private

x=ax-ab

Quote

Private

Delete

Make sure x=x , so we know that a=1, and to make ab=0 ,b must equal to 0

Quote

Private

Delete

The logic behind x=x? First thing I thought was that x should have a degree of 2 in order to have more than 1 solution.

Quote

Private

Delete

X=X means, it can have ANY number of solutions

Quote

Private

Delete

Any number can be equal to any number, very simple logic

Quote

Private

Delete

For linear equation, this was my thought process

Quote

Private

Delete

Notice that x/a = x - b represents a linear equation with one unknown, x. Generally, such equations have one solution for x. For instance, x/2 = x - 1, which has one solution: x = 2. Similarly, x/4 = x + 3 also has one solution: x = -4. The only way for x/a = x - b to have more solutions is if the left-hand side and the right-hand side are identical, resulting in x = x, which is true for all values of x, hence more than one solution. This could happen if a = 1 and b = 0, thereby leading to x = x, and infinitely many solutions for x.

Hey Guys
can anyone help me with this? Like how will you approach this type of question ?

In a certain company, all employees are either beta employees or standard employees. In this company, 25% of the beta employees and 17% of the standard employees participate in the voluntary equity program. Let S be the number of standard employees. If there are 600 employees total, what is the value of S?

(1) S > 100

(2) more than 130 employees participate in the voluntary equity program

Maybe E?

I think E
As We don’t have a clear value of both parameters S and N(numbers of participants in a program)
S can then take many values
A+S=600
25/100A+17/100S =N

Condition 1— S>100
Condition 2 — N>130

Please helps me to understand what’s going wrong with my reasoning here.

X/a = X-b
X= aX-ab
X(a-1)= ab
X= ab/(a-1)

Here the only way for X to have more than 1 solution , the denominator have to be equal to 0
Then a=1
(a-1)=0
ab/0 = infinite

And the numerator has to be different to zero to avoid 0/0( undetermined form)

as a=1 b just has to differ to zero

I don’t have a clear value of b

You cannot divide x(a - 1) = ab by (a - 1) precisely because (a - 1) can be 0. Hence, writing x = ab/(a - 1) would be incorrrect.

Check the thread. I have given a reply on it. Otherwise n means the shows in first n years. In these n car shows the cost was 10 and 12 but after that the price increases for each regn.

curiousPope, answer will be 3 and 3. I’ll talk of second part. The important point is common use at SAME TIME, and you can see between 1700 & 1800, there are three B, C and D together. Thus 3 techniques at same time.

There was a PM too. So, I am addressing the question here itself. X has to be followed by Y. First monday is not followed by cleaning on first tuesday. Similarly, streets would be cleaned on 2nd and 3rd Monday but it will not be followed by Y. Only on fourth Monday and fourth tuesday, the cleaning of street will be done on consecutive days. Catch words are EVERY Monday and FOURTH Tuesday.

https://gmatclub.com/forum/two-bicycle- ... 28866.html

Quote

Private

Hi Bunuel- I think answer should be C, but I am not sure.
Firstly, I assumed A=x and B=3x from Statement 1 but since I do not have actual speeds, Statement 1 wasn’t sufficient to determine the time in seconds.
Secondly, the average speed would not be of much help either from Statement 2. So, not sufficient
Lastly, putting the two statements together and applying avg speed formula- (2*S1*S2)/(S1+S2) to get the avg speed of each wheel.
Hence, concluded the both statements together are sufficient to answer the question.

Is my approach correct?

Also, if we solve further would the answer be 6 3/4 seconds using relative distance/relative speed concept?
