Official Solution:

Out of 320 people, 75% like talk-show 1 and 65% of the people who like talk-show 1 also like talk-show 2. If there are no people who like talk-show 2 but do not like talk-show 1, how many of the 320 people do not like talk-show 2 ?

A. 72
B. 84
C. 120
D. 156
E. 164

The number of people who like talk-show 2 \(= 320*0.75*0.65 = 156\). The number of people who do not like talk-show 2 \(= 320 - 156 = 164\).

Answer: E

@Bunnel : I am not sure of my understanding but does the question ask to find X + 84 ?

Talk show 2 and Talk show 1 = 320*0.75*0.65 = 156.

Does this statement ' If there are no people who like talk-show 2 but do not like talk-show 1' mean people only liking talk show 2 = 0 ?
