a total of 30 percent of the geese included in a certain migration study were male . if some of the geese migrated during the study and 30 percent of the migrating geese were male , what was the ratio of the migration rate for the male geese to the migration rate for the female geese ? [ migration rate for geese of a certain sex = ( number of geese of that sex migrating ) / ( total number of geese of that sex ) ]
"let ' take the number of geese to be 100 . male = 30 . female = 70 . now the second part of the q , let ' s take the number migrated to be 20 . so we have 20 geese that migrated and out of that 20 % are male i . e 20 / 100 * 30 = 6 geese ( males ) and now we know out of the total 20 geese , 6 are male , then 14 have to be female . now the ratio part , male geese ratios = 6 / 30 = 1 / 5 . - a female geese ratios = 14 / 70 = 1 / 5 - b cross multiply equations a and b and you get = 1 . ans d"
