The minimum 2a can take is 9.2 and maximum value a can take is 8.5, hence 2a can take is 17. So the minimum range will be 9.2 - 3.7 = 5.5 and maximum range is 17 - 3.5 = 13.5; So C,D,E fits between 5.5 and 13.5, hence answers. GRE Instructor Joined: 10 Apr 2015

The six numbers shown are listed in increasing order. Which of the following values could be the range of the six numbers?

Indicate all such values.

A 4.0
B 5.2
C 7.3
D 11.6
E 12.9
F 14.1

Let's examine the two EXTREME values of a.

Case a: The SMALLEST value of a
If the values are strictly increasing (i.e., no values are equal), then a could be a little bit smaller than 8.5.
So, a could equal 8.499999999999
For all intents and purposes, let's just say that the a COULD equal 8.5
In this case, 2a = 9.2, which means the range = 5.5

Case b: The GREATEST value of a
If the values are strictly increasing (i.e., no values are equal), then a could be a little bit bigger than 4.1.
So, a could equal 4.10000000001
For all intents and purposes, let's just say that the a COULD equal 4.1
In this case, 2a = 17, which means the range = 13.3

Now that we've examined the EXTREME cases, we can see that the range can be between 5.5 and 13.3

If in the first case a = 8.5, how could it be that 2a = 9.2? And the same is in the second case, a = 4.1, how 2a could be equal to 17?

We need to find the range here.
the range will be bigger than 9.2 - 3.7 = 5.5
and smaller than 8.5*2 = 17 - 3.7 = 13.25. Re: The six numbers shown are listed in increasing order. Which   [#permalink] 04 Sep 2018, 18:49
