CAT-2003-Previous Years Paper
A survey on a sample of 25 new cars being sold at a local auto dealer was conducted to see which of the three popular options —— air conditioning, radio and power windows were already installed.
Following were the observation of the survey:
I. 15 had air conditioning
II. 2 had air conditioning and power windows but no radios
III. 12 had radio
IV. 6 had air conditioning and radio but no power windows
V. 11 had power windows
VI. 4 had radio and power windows
VII. 3 had all three options
What is the number of cars that had none of the options?
Total = 4 + 6 + 2 + 2 + 3 +1 + 5 = 23
∴ Cars having none of the option = 25 – 23 = 2.
