BRAINTEASER: This Week's riddle: (via www.theengineer.co.uk) 


When some day-trippers started off on their annual seaside trip, each minibus carried exactly the same number of people.

Half way there, 10 minibuses broke down, so each remaining minibus carried one more person.

On the way back, 15 more minibuses broke down, so there were 3 more people in each minibus than when they started out in the morning.
How many people went to the seaside and in how many minibuses?
