Question

A survey was conducted among 100 students of age groups 7−12 years and 13−18 years to find their favorite book genre. The students had to select any one genre out of detective, adventure, and biography. Out of the 50 students in the age group 7−12 years who participated in the survey, 23 liked adventure or biography. The total number of students of both age groups who liked detective books was 28. Using a two-way table, compute the total number of students in the age group 13−18 years who liked adventure or biography. 23 27 49 51
