CAT 1996 | Question: 135

Question

In a locality, two-thirds of the people have cable-TV, one-fifth have VCR, and one-tenth have both, what is the fraction of people having either cable TV or VCR?

• A. $19/30$ 
• B. $3/5$
• C. $17/30$ 
• D. $23/30$

Answer 1

Fraction of people who watch cable tv only= (2/3 - 1/10) = 17/30

Fraction of people who watch VCR only = (1/5 - 1/10) = 1/10

Therefore fraction of people who watch either cable or vcr = 17/30 + 1/10 =  20/30 = 2/3

So 2/3 is the Correct answer.
