(a/b) (c/d) > c/b?
or (a/d)(c/b) > c/b
as c,b are positive,
thus a/d>1 or a>d???
c>b. insufficient
a>d sufficient
IMO B
or (a/d)(c/b) > c/b

Statement 1: c/b>1786 wrote:If a, b, c, and d are positive integers, is (a/b) (c/d) > c/b?
(1) c > b
(2) a > d
LHS = ac/bd
or, (a/d)(c/b) -- no info about a/d.. hence, statement 1 is NS
statement B says a/d>1 .. say for example 2
2*C/b will always be greater than c/b
Hence, statement 2 is sufficient.
Correct answer - B
