Can someone help with this quant comparison problem?

ab > 0 and bc < 0

Quantity A) ac

Quantity B) 0

What have **you** done to try to solve this problem?

oh i got the answer now.

If ab > 0 then there are two cases 1) a & b both are + or 2) a & b are both negative

and similarly if bc < 0 then there are 2 cases 1) b is + & c is - or 2) b is - & c is +

So in both cases ac and c would have opposite signs which will be a negative no. So basically Qty B is greater.
