Even if we combine both the statements, we can not infer whether CD > BC because:

Let AB = CD = x
AD = 20
Hence, 2x+BC = 20
or BC = 20- 2x

We are asked to determine if CD > BC which implies if x> 20-2x
or 3x> 20
or x> 20/3 ?
And we do not know the value of x.
Hence, Statement 1 and 2 together also are insufficient to answer the question.

Let AB =x BC=y and CD=z therefore AD =x+y+z and the question stem is , IS z>y? from statement 1 x+y+z=20 hence we dont know the individual values NS. statement 2 say that x=z but there are no numerical values NS. 1+2 together 2z+y=20 and we cannot find the individual values, Hence E. Let me know if my method is correct. Thank you

(1) AD = 20
(2) AB = CD

1) given the either length so NS
2)ab=x bc=k Ccd=x //no idea of the length of line so NS
1+2 2x+k=20
if x=5 K=10 bc>cd
if x=9 k=2 here cd>bc
Hence option E

What IF: (a little changed version)
In the figure above if the distance is in integer mode, is CD > BC ?

(1) AD = 3
(2) AB = CD
The correct answer is D, right? IanStewart?

Why do you think Statement 2 would be sufficient alone in that question?

Oh, it is my bad-i've mistakenly correlated statement 1 (total distance is 3) when i tried to solve statement 2! Ok, it is A.

Wait, I’m so confused. I thought the question is C*D>B*C..
Are we dealing with the DISTANCE between C and D and B and C?
What a kind question.. geez

a simple question and can probably solve without pen and paper. Let's give it a go

statement 1: doesn't really tell us much about CD and BC individually. Not sufficient.
statement 2: again, no real information; this time, not even a number as in B. Not sufficient. So A,B and D are off.

Combining the 2 statements: as we can that the line AD can be divided into 3 parts. Let's say AB= x, this will mean CD =x (statement B). No info on BC so let it be y.
2x+y=20... we can't solve this unless we have another equation with the same variables.

The final Answer is E.

Key here was to realise not to assume that the 3 parts are of equal length even thought it may look like that in the diagram. Wait for the question to say that explicitly

Hey, can someone clarify the question?
is it a number line question? I thought B alone was sufficient
