The correct answer is C. 49.
Remember that there are 100 students divided into 7-12 and 13-18 age group. So there should be 50 for each. The table should go like this:
7-12 age group
23 adventure or biography
27 - detective
so you just have to subtract 50 from 23, which makes it 27. The remaining belongs to the 13-18 age group.
13-18 age group
1 - detective
49 - adventure or biography.
81 = 37.5% of x.
81 = (37.5/100)*x
81 = 0.375x
0.375x = 81
x = 81/0.375
x = 216
The number is 216.
