The Geese Problem: " A flock of geese on a pond were being observed continously. At 1:00pm, 1/5 (or 20%) of the geese flew away. At 2:00pm, 1/8 (12.5%) of the geese that remained flew away At 3:00 P.M., 3 times as many geese as had flown away at 1:00pm. flew away, leaving 28 geese on the pond. At no other time did any geese arrive or fly away or die. How many geese were in the orginial flock?"
