I guess you are referring to the fact that sum of two sides > third side? What is QR 2nd DS150? I have the green book for quant review, there is no 150 in DS there... _________________

I suppose the Logic given by @mainhoo is perfect. Even if it adds to 14, then even 15 is not possible. Lets take it this way..If all points are assumed to be in straight line, then only PT can attain its maximum length. So its clear that PT=15 is not possible. Rest all values can be obtained at different configuration. _________________

Here is my version ...

Step1: Given: PQ = 3, QR = 2 So, Using Traingles Sides theorm, PR can be: > (3-2) & < (3+2). i.e, PR can be >1 && <5. So, possible values for PR are: 2, 3, 4

Step2: Given: RS = 4, ST = 5, So, RT can be >1 && < 9 So, possible values for RT are: 2, 3, 4, 5, 6, 7, 8

Step3: PRT forms a traingle From Step1: PR can be: 2, 3, 4 From Step2: RT can be: 2, 3, 4, 5, 6, 7, 8 So, PT can take values till less than 12.

Answer: 5 & 10 are possible but 15 is not possible. The maximum side has < 12 (i.e, 8 + 4)

Cheers! Ravi

put the 4 segment for which you know the length in a straight line...that's the limit configuration and it gives you the maximum length of the 5th segment is <14.

Something like this:

P---Q--R----S-----T

Then you will see that by bending the segments of the line all values <14 are possible for the 5th side.

Answer is C i.e. 5 and 10 because the sum of all the other sides is 14 and one side can never be greater than sum of other sides _________________
