In a club, there are 58 members. Among them, 25 members drink tea, 23 members drink coffee and only 7 members drink both tea and coffee. What is the ratio of the number of members who drink tea or coffee but not both, to the number of members who drink neither tea nor coffee?

- D2 : 1
Explanation
Members drinking only tea or only coffee (not both) = 25 + 23 − 2×7 = 34. Members drinking at least one = 25 + 23 − 7 = 41, so those drinking neither = 58 − 41 = 17. The required ratio is 34 : 17 = 2 : 1. Hence option D is correct.
