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. The survey found

• $15$ had air conditioning
• $2$ had air conditioning and power windows but no radios
• $12$ had radio
• $6$ had air conditioning and radio but no power windows
• $11$ had power windows
• $4$ had radio and power windows
• $3$ had all three options.

What is the number of cars that had none of the options?

1. $4$
2. $3$
3. $1$
4. $2$

From  the Given conditions we have,

when we add all the values We get a total of 23 cars.

So 2 cars don't have Air Conditioning or Radio or Power Windows

Hence (D) 2 is the Answer.
