Out of 120 applications for a post, 70 are male and 80 have a driver's license. What is the ratio between the minimum to maximum number of males having driver's license?
70 male means 120 - 70 = 50 female
For a maximum, all 70 male can have driver's license.
For a minimum: If all 50 females posses driver's license, then the remaining 30 licenses can be possessed by males.
Min to max = 30 to 70 = 3 to 7
The correct option is B.
