To amuse themselves during lengthy missions, astronauts often turn on the zero gravity and play darts. Buzz Aldrin holds the record score of 100. What's the minimum amount of darts he needed to throw to reach that score on the board shown to the left? dartboard 4 circles starting from the outside 1st circle 18 2nd circle 17 3rd circle 39 and 4th circle 40
I cannot find any combination of those 4 numbers that will add up to exactly 100. Are the facts given correct.
Using 39 or 40 you cannot make 61 or 60 , 6x17 =102, 40+40+18 =98.
