How would you rephrase this statement? WOuld you apply transitive properties for these sort of problems??PLease show your workings..Thanks

ac/bd > c/b ??

Since we know a,b,c,d are positive integers,we can rephrase the question stem as

a/d > 1 ?

Statement (1) insufficient. does not gives us relation ship between a and d

Statement (2) a>d. If numerator is greater than denominator, then a/d will always be greater than 1. Sufficient.

Hence B.

Whats the OA?

I bet OA is B

I used a little bit another reasoning, but parallel_chase's approach is faster

(a/b) (c/d) > c/b
is the same as
(a/d) (c/b) > c/b

as c/b are equal to increase left part we need a/d to be more that 1, or a>d

only B gives this

what is OA?
I am getting B

I am also for B

qn can be simplified fo
is a>d
and B says this only

OA - B. Thanks guys!
