Members of a Jalandhar sports club are shown in the diagram; the number outside plays none of the three. How many members play at least one game but not all three?

Question

Accepted Answer

55. At least one but not all three = every part inside the circles except the centre: 15 + 12 + 10 + 6 + 5 + 7 = 55. 58 keeps the 3 in the centre, 64 also adds the 9 outside, and 37 counts only exactly one.
