Let's say there were 100 geese in study.
30 were male.
70 were female.
Now say, some migrated during study i.e. X
Male migrated during study = 0.2 X
Female migrated during study = 0.8 X
Ratio = (0.2 X / 30 ) / (0.8 X / 70 )
= 7 / 12
Answer (B)

hi Bunuel,
I did this by taking total geese = 100
30% male = 30
so 70% is female, which is 70
Then i assumed the migration to be of 50;
20% of 50 = 10 males
so rest 40 to be females
migration rate = 10/30:40/70
so answer is 7/12
is this approach right? can we assume the migration number as well?
Also, if the question didn't mention that migration of certain geese of sex = no of geese of that sex/total geese of that sex, i would have taked the migration rate of male to migration rate of female to be 10/40 = 1/4, is that how should one perceive or am i wrong here?
Your thoughts please
