In a recent traffic drive, the Delhi traffic police started fining cars which have any of the three faults- faulty headlights, faulty papers, and faulty number plate. On the Delhi-Jaipur highway, there are three check posts- check post 1, check post 2, check post 3, in that order. The cars are first stopped at check post 1, then at check post 2 and then at check post 3. The table below shows the number of cars fined at each check post for a given fault on a particular day. Each car has at least one of these three faults. At each check post, a car is fined for one fault only. If a car is fined for a particular fault at a check post it is not fined for that fault at the subsequent check post(s). A car leaves a check post without getting fined only if it has already been fined for all its faults.
