A) Quantity A is greater.
B) Quantity B is greater.
C) The two quantities are equal.
D) The relationship cannot be determined from the information given.
Ok..
Too many variables.. What do we do? - we try to remove as many variables as possible..
|a|∗b3∗c2∗|d|∗e5∗f6∗g<0Of course we cannot find the values of variables but it can tell us what all lead to a NEGATIVE value..
so discard the positive terms as they do not affect the equation..
|a|∗b3∗c2∗|d|∗e5∗f6∗g<0...........b3∗e5∗g<0Now whatever be the values of b, g and e,
b∗g∗e<0With this information let us see if we can compare A and B.
g(|a|∗b∗e))(
g(b∗e∗|d|)
Now both have three terms same, so we compare |a| and |d| and we know |a|>|d|, so the numeric value ||a|*b*g*e|>||d|*b*g*e|
BUT since b*g*e<0 both A and B are NEGATIVE..
We know larger the negative value, the smaller it is.
so |A|>|B| hence A<B..
B
