B) 12.5%

Let there be 100 motorists on the road. 10 get speeding tickets.
Let number of motorists who exceed speed limit = x
Given 80% of x= 10
So x= 12.5

The question says that 20% of those who exceeded the posted speed limit did not get a ticket, which means 80% of those who did got a ticket.

It says that 10% the motorists exceed the posted speed limit and receive speeding tickets.

So you can equate the two.

Let the number of motorists, m be 100.

10% of m = 10 (those who speed and get a ticket)

Let the number of motorists who speed be s

Therefore, if 20%(s) = no. of motorists who speed but do not get a ticket, no. of motorists who speed and get a ticket = 100%(s) - 20%(s) = 80%(s) = 10

Therefore, if 80%(s) = 10; s = 12.5 people = 12.5% (when m = 100)
