Monthly Brain Teaser and last months answersThursday, September 9th, 2010
Last month you were given this problem:
A horse dealer in the wilds of the Pennines died, leaving in his will a herd of 60 horses, all of equal value. He left one third of the herd to his wife, one quarter to his eldest son, one fifth to his other son and one fifth to his daughter. Unfortunately when they went down to the yard to take their share, they found that one of the horses had died, leaving only 59. They were all wheelers and dealers, so spent the day arguing about the fairest division of the herd. Fortunately their vet, who was riding by, saw what was happening, came and solved the problem for them, then rode off into the sunset leaving them all happy. What did he do?
Well, it was quite simple really. The vet put his own horse into the yard with the rest of the herd, bringing it back up to 60. The wife then took her 20 horses, eldest son 15, youngest son 12 and daughter 12, leaving one horse – the vet’s – which he mounted and rode off, leaving his bill for veterinary advice. Obviously you all got that.
Now one for this month – no paper, pencils or calculators allowed. How much earth is there in a trench that is 3 feet 3 inches wide, 2 feet 6 inches deep, and 10 yards long?
More next month.
