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.

x=ax-ab

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

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.

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

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

For linear equation, this was my thought process

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

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.

The answer should be C. Is this answer correct?
