Answers and Solutions for Venn Diagram Problems and Solutions for CAT PDF:<\/strong><\/p>\n

1)<\/strong> Answer (C)<\/p>\n

Let the number of days in the vacation be x
\nThey played tennis for x-14 days
\nThey did yoga for x-24 days
\nSo, they did yoga or played tennis for x-14+x-24 = 2x-38 days
\n2x – 38 = 22
\n=> x = 30<\/p>\n

2)<\/strong> Answer (C)<\/p>\n

Number of people owning exactly 2 articles = 9
\nNumber of people owning exactly 3 articles = 1
\nApplying AUBUC formula, we get
\nAUBUC = 22+15+14 – 9 -2*(1)=40
\nNumber of people who do not own any article = 50-40 = 10<\/p>\n

3)<\/strong> Answer (B)<\/p>\n

Let a be the number who watch only one channel, b be the number who watch only 2 channels and c be the number who watch all channels.
\na+b+c = 100
\na+2b+3c = 80+22+15 =117
\nSubtracting both equations,
\nb+2c = 117-100 = 17
\nMaximum c occurs when b = 0
\n2c = 17
\nc = 8.5<\/p>\n

4)<\/strong> Answer (A)<\/p>\n

Applying AUBUC formula
\nLet x be the number who watch BBC and CNN and y be the number who watch all three channels.
\n100 = 80+22+15-(10+5+x)+y
\nx-y = 2
\nHence only 2% people watch BBC and CNN only.<\/p>\n

5)<\/strong> Answer (D)<\/p>\n

Applying AUBUC formula<\/p>\n

Let x be the number who watch BBC and CNN and y be the number who watch all three channels.
\n100 = 80+22+15-(10+5+x)+y
\nx-y = 2
\nWe cannot find the exact value of y.
\nHence, the answer is “cannot be determined”.<\/p>\n
