Answer 1

Step-by-step explanation:

total = 170

tv = 115

r = 110

mg = 130

tv and mg = 85

tv and r = 75

r and mg = 95

tv, mg and r = 70

Maximum no. of people who watch any two things = 170 - 70 = 100

Maximum no. of people who watch tv with some other thing = 85

Maximum no. of people who watch r with some other thing = 95

Maximum no. of people who watch mg with some other thing = 95

1) Only tv = 115 - 85 = 30.

2) Only r = 110 - 95 = 15.

3) tv and mg without r = 85 - 70 = 15.
