Readers of three magazines in Pune: the note gives each magazine's total, and the diagram gives those who read exactly two and those who read all three. How many people read at least one magazine?

Question

Accepted Answer

95. Only Arts = 48 - 9 - 7 - 4 = 28, only Business = 40 - 9 - 5 - 4 = 22, only Cinema = 36 - 7 - 5 - 4 = 20. At least one = 28 + 22 + 20 + 9 + 7 + 5 + 4 = 95. 103 forgets that the centre is counted three times in the totals, 99 removes it only once, and 124 just adds the totals.
