The range for a list of measurements equals the greatest measurement minus the least measurement. The two lists of measurements, \(X\) and \(Y\), combined consist of 30 measurements with a range of 25. What is the range for the measurements in list \(X\)?

1) The range for the 12 measurements in list \(Y\) is 20.

2) List \(X\) consists of 18 measurements.

[quote="Sallyzodiac"]The range for a list of measurements equals the greatest measurement minus the least measurement. The two lists of measurements, \(X\) and \(Y\), combined consist of 30 measurements with a range of 25. What is the range for the measurements in list \(X\)?

1) The range for the 12 measurements in list Y is 20.

2) List X consists of 18 measurements.

answer to this question is E as both statements are not sufficient to tell you the answer

statement 1 tells that The range for the 12 measurements in list Y is 20 but that tell cannot tell you the range of x
take lowest number in list y= 1 and highest 21 and take all the nos in list x as 26. That will give you range of x =0
take lowest number in list y 1 and highest 21 and take lowest number in list x= 22 and highest =26 .That will give you range of x =4
two different answers so the statement is not sufficient.

statement tells only about the nos in list x but no additional information so not sufficient.

by combining both statements we are not able to get any answer.

So we are given 2 lists, X and Y and we are given that the
1. the total number of measurements is 30. X(n) + Y(n) = 30.
2. Largest measurement - Smallest Measurement = 25

But we are not told the number of measurements in either X or Y. We also don't know whether the largest of smallest measurement of the combined range belongs to X or Y.

We need to find the largest measurement of X and the smallest measurement of X for our answer.

1) 1) The range for the 12 measurements in list Y is 20.
Okay so we know that Y has 12 measurements, therefore X has 18. And we know the Y(largest)-Y(smallest) = 20 INSUFFICIENT

2) List X consists of 18 measurements.
We are told the X consists of 18 elements. We already figured this out in Statement 1 as well. It again does not tell us anything further. INSUFFICIENT

Answer is E

1) The range for the 12 measurements in list Y is 20.

2) List X consists of 18 measurements.


Here There are 30 measurements in x and y.
Range of 30 measurements is 25.
Range of x=?
First of all we need to know the elements that are present in x.

Statement 1:
From 1 we got to know that y has 12 measurements and x has 18.
Now Y has range 20:
we don't know what are the elements that make the range 25 overall and we don't even know the elements in x to find the range of x.

Statement 2:
Same problem as A in statement 2.we don't know the elements.

From 1+2.
we don't know any extra information.
So, the Answer is E

Lets say, the least number from the 2 lists is x. Then the biggest number from 2 lists will be (x + 25).
Statement 1: We cannot find the biggest and the smallest measurement in X from the given information. So, we cannot find the range of X. Hence, Insufficient.
Statement 2: No of measurements in list X doesn’t alone provide us with the range of X. Hence, Insufficient.
Statement 1 & 2 together: Information given in both the statement doesn’t help us in finding the range of X unless we are given that the smallest and the largest number of both the lists lie in X. Hence, Insufficient.

Hi Sallyzodiac,

I feel like I am going crazy trying to solve this easy problem but am getting stuck. Could someone provide a detailed step by step method for solving this? Thank you so much!

2) List \(X\) consists of 18 measurements.


To get the range of the list X , we need the maximum value and the minimum value in the list.

From statement 1 , we know the range of 12 measurements in list Y . So , if the first measurement is 100 then the last measurement is 120. But we dont know anything about the maximum or the minimum value in the list Y.

From statement 2 also , we don't know anything about the maximum or the minimum value in the list X.

Taking both together , we still don't know anything about the maximum or the minimum value of the list X.

Option E is the answer.

PLease give me KUDO s if you liked my answer.
