1. We don't know individual values. So insufficient.

2. We know only the ranges. Value can be anything. So insufficient

1+2 salaries are 0,6300,12600,18900,25200,31500

6300,12600,18900,25200,31500,37800

So any values possible. So insufficient

Hence E

ashisplb why would anyone do a job for zero salary ?
In fact it could be any value for the least paid and the increment of 6300 then on

x, x + 6300, x + 2 * 6300, x + 3 * 6300, x + 4* 6300, x + 5 * 6300
Avg = ( x + ( x + 5 * 6300 )) / 2
= ( 2x + 5 * 6300 ) / 2
No information about x
Insufficient

(2) The range of the 6 annual salaries is $31,500.
No information about individual salary
Insufficient

Combining both :
No new information, St 2) can be derived from St 1) itself
Insufficient

Hence, E.

Hi,

Stmt1 : Lets say we try to find the salary of six emp. Then it can be calculated by X(n)=X(n-1)+ 6300
So the sixth salary will be X(6)=X(1)+5(6300)
or X(6)-X(1)= 31,500
Insufficient.

Since 1 and 2 are both the same statements, So choice E

NEW question from GMAT® Quantitative Review 2019


(DS03615)


The average = Sum of salaries/6

Let first salary be x

The next salary will be x + 6,300 and so it goes to the 6th salary that equals x + 6,300*5

We have one variable that we don't know

Insufficient.

Statement 2)

Tells us the range X6 - X1 = 31,500

So we don't have anything specific about the salaries. Insufficient.

Now combine

The range is basically X6 - X1 = x + 6,300 *5 - x = 31,500

Basically tautology.

We don't know the value of x.

Insufficient.

Answer choice E

Statement (1) basically says " the range is 31500. We should paraphrase the disguise language. If both statement says the same thing then the answer must be (D) or(E)
