Problem 2
Problem 2 The All Saints Choir.
Ann, Bethan, Charles and David decide they will total up the number in
the choir for the four Sundays in November. Ann gets a total of 22,
Bethan gets a total of 24, Charles gets a total of 27, and David gets a
total of 20. At first they wonder why they each have a different
answer, then they realise that each has only been at church on three
out of the four Sundays. Ann missed the first Sunday, Bethan missed the
second Sunday, Charles missed the third Sunday and David missed the
last Sunday. How many people were in the choir on each Sunday in
November?
