1. CD is not known.Insufficient 2.AB is not known. Insufficeint 1+2 > > AB+2(BC)+CD=12 >> AD+BC=12 BC is not known. Insufficient E

Determine the length of AD? Statement 1: AC = 6 We don't know CD  Insufficient Statement 2: BD = 6 We don't know AB  Insufficient Combining 1&2: AC + BD = 12, here BC is accounted twice and since we don't know BC  Insufficient Answer E

First thing you need to understand after looking at the figure position of points related to each other is not given. DO NOT ASSUME.
S(1): Tells nothing about CD hence N.S S(2): Tells nothing about AB hence N.S
Event after combining we do not know distance between B & C which could be 6 or 0.01 . Hence Not sufficient.
I think this could have been a little more trickier if we were asked maximum length of AD will always be smaller then which number. The answer would be 12 assuming B&C are very close to each other and even if they are on top of each other the maximum length can be 12.

(1) AC = 6 (2) BD = 6 Kudos for a correct solution.AD = AB+BC+CD From Statement 1: AC =6; AD = 6+CD(We cannot find using given information) Statement 2: BD = 6; AD= 6+AB (Again, We cannot find using given information) Combining both also not sufficient to find the value Ans : E

(1) AC = 6 (2) BD = 6 Kudos for a correct solution.The correct answer is E. Hi Bunnuel, My soln was: AD = AC + BD  BC (as in AC + BD , BC is already counted) NOw as AC=BD = 6, both points B and C are same. ( Taking St 1 and St 2 together) so AD = 12. Can you Pls. guide me where I went wrong?

Can you Pls. guide me where I went wrong? The red part is not correct. Consider AB = 5, BC = 1, and CD = 5 OR AB = 4, BC = 2, and CD = 4.

(1) AC = 6 (2) BD = 6 Kudos for a correct solution.Attachment: 20141222_1955.png We can also solve this question by taking AB=x, BC=y, CD=z. So we need to find AD, which is x+y+z Statement 1: Gives us x+y = 6, so it is not sufficient. Statement 2: Gives us y+z = 6, so again not sufficient. Combining, we can add the two, we get: x+y + y+z = 6+6 OR x+y+z + y = 12 Unless we know y, we cannot find x+y+z. So not sufficient. Hence E answer
