Hi sairam595,

Word problems on the GMAT can be really tricky. The best thing to do when you solve word problems is to read the question in parts rather than reading the entire question. Also keep in mind that when you deal with questions related to percentages, it always makes sense to start with an initial value of 100.

So lets work this question out part by part.

40 percent of the ducks included in a certain side effects study were maleNow if we assume the total number of ducks to be 100, then we have

40 male ducks and 60 female ducksIf some of the ducks had side effectsLet the number of ducks who have side effects be 's'.

30 percent of the ducks who had side effects were maleThis means that the number of males who had side effects is

0.3s and the number of females who had side effects is

0.7sWhat was the ratio of the side effect rate for the male ducks to the side effect rate for the female ducks?The side effect rate for male ducks = Number of male ducks with side effects/Total number of males ducks ----->

(0.3s)/40The side effect rate for male ducks = Number of male ducks with side effects/Total number of males ducks ----->

(0.7s)/60Ratio = (0.3s)/40 : (0.7s)/60

Simplifying we get

9/14Hope this helps!
