Let M represents males and N represents other than males
So M = 70 and N = 50

Now 80 have driving license..

(1) For max males
all the M = 70 males having license, then rest 10 other than males having license
(2) For min males
first all the N = 50 having license, then rest 30 males having license

So MAX = 70 and MIN = 30
Ratio is 30:70 or 3:7

Answer
3:7
