Data Sufficiency

Hi,

Does anyone know how to solve this problem?

Thanks

ack

stmt 1 - this gives that C is b/w A and B and also in the middle point...But no info D..........So insuff

stmt 2 - this just gives that A is left to D but dont provide any info of distance from A to D or another info to solve the pblm....So insuff

both - C is b/w A and B....and D is left to A...Here itself there can be two combinations

A D C B
OR
A C D B

NOTE - When it comes to Qs like these we always need to consider both directions...PLEASE DO NOT SET YOUR MIND IN JUST ONE DIRECTION....

So even both stmts wont suffice.....Hence ans is E
