For a group of 200 persons, 100 are interested in music, 70 in photogr...
Given:
Total number of persons = 200
Number of persons interested in music = 100
Number of persons interested in photography = 70
Number of persons interested in swimming = 40
Number of persons interested in both music and photography = 40
Number of persons interested in both music and swimming = 30
Number of persons interested in photography and swimming = 20
Number of persons interested in all three - 10

To find:
Number of persons interested in photography but not in music and swimming

Solution:
Let's make a Venn diagram to understand the given information.

From the diagram, we can see that:
Number of persons interested in music only = 100 - 40 - 30 - 10 = 20
Number of persons interested in photography only = 70 - 40 - 20 - 10 = <70-40-20-10=0>>0
Number of persons interested in swimming only = 40 - 30 - 20 - 10 = <40-30-20-10=0>>0
Number of persons interested in photography but not in music and swimming = 20

Therefore, the correct option is (d) 20.
