Total = 290
Daily times D = 181
Guardian G = 142
Punch P = 117
Read None = 0
Daily Times, and the Guardian D∩G = 75
Daily Times and punch D∩P = 60
Guardian and punch G∩P = 54
All three papers = D∩G∩P
Total = D + G + P - D∩G - D∩P - G∩P + D∩G∩P
=> 290 = 181 + 142 + 117 - 75 -60 - 54 + D∩G∩P
=> D∩G∩P = 39
39 read all three news papers
Exactly two of the papers = 36 + 21 + 15 = 72
Guardian Alone = 52
