Remember b could be positive or negative number.Question is whether or not a>c.

Lets look at the statements

Statement 1 : a/b>c/b,if b=positive number(like 1,0.5,3,4/7,5,6 etc) we can simplify this inequality by multiplying both side b , as

a>c but,if b=negative number(like -1,-0.5,-4/7,5,6 etc) if we want to simplify we must have to alter the inequality as

a<c Statement 1 is not sufficientStatement 2 : the reasoning of this statement is same as statement 1,like this,

5ab>6bc,if b=positive number (like 1,0.5,3,4/7,5,6 etc) we can simplify this inequality by multiplying both side b, as

a>6/5 c (single amount of a is greater more than greater amount of c)

but,b=negative number(like 1,0.5,3,4/7,5,6 etc) we have to reverse the sign of inequality as

a<6/5 c Statement 2 is not sufficientSince any of this two statement solve the issue whether or not b is positive or negative.My

Correct Answer is E
