• 'How many children?'

At the local Sunday School meeting, the teacher brought in some puppies. There were 20 more children than puppies. In the corner of the room, within the ant's nest, there were exactly 10 times as many ants as children. In total, including the teacher, the children, the puppies and the ants, there were 1,440 legs in the room. How many children attended?

Last week's answer to Sum Day Soon

A) The last sum day of the 21st century is December 31, 2043, because 12+31=43, and both the month and day are as big as possible.

B) This one is much easier than you might think. The correct answer is 365, because every day in a standard (non-leap) year is part of a sum day for some year. For example, November 26 is a sum day for the year 2037, because 11+26=37. The only date for which this principle doesn't work is the leap day, February 29. That's because 2+29=31, but 2031 is not a leap year.
