As non-runners count, I reckon you have 2 singles, 3 doubles and 1 treble EW to collect on - EW odds will depend on number of runners. But it should be a decent sum. 50/1 single £5.10, 40/1 single £4.10, same for 2 doubles with NR, double 2 winners £209.10, same for treble. Not bad!
One of your winners must have been in a race that returned one quarter odds for a place, the other in a race that returned a fifth odds for a place.
Your winning singles come to £9.30. Your Winning doubles come to £218.30 and your winning treble returns £209.10. Total for your winning bets is £436.70.
If your 50-1 shot returned one quarter odds your place bets come to £28.90 – Total £465.60. If the 40-1 winner returned one quarter odds your place bets come to £28.70 – Total £465.40.
BTW - I settled the bet with pencil and paper in about thirty seconds. I managed a betting shop for about seven years in the Seventies. A good settler (which I think I was) in those days would deal with 4-5,000 bets on a Saturday, of which about 20% would be winners.
