20% of those who exceed speed do not receive tickets

Therefore, 80% of those who exceed receive tickets.

This 80% is given to be 10% of total ( 10 percent of the motorists exceed the posted speed limit and receive speeding tickets)

80%(Exceed & Receive ticket) = 10% Total

Therefore, 100% ((Exceed & Receive ticket) = 12.5% (Total) B

i plugged in numbers.... so there are 200 motorists and so 20 are speeding and get tickets (10%)
if 20% of the speeding motorists do not get tickets means that 80% of them do get tickets and 80% corresponds to the 20 motorists. 80% is 4/5
four 5s make a 20 ... so the remaining must be another 5 .. so 25 motorists correspond to 100% of the total motorists who are speeding
and so 12.5 % (25/2) of the 200 motorists are speeding.

but i guess doing the algebraic way is much easier in this Q
