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

Hi, Stmt1 : Lets say we try to find the salary of six emp. Then it can be calculated by X(n)=X(n1)+ 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 Probus

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) Posted from my mobile device
