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 radios.
6 had air-conditioning and radios but no power windows.
11 had power windows.
1 had radio and power windows.
3 had all three options. What is the number of cars that had none of the options?

Options

A. 4
B. 3
C. 1
D. 2

Answer

D

Explanation

According to the question
Total number of cars = 25
Then, total number of cars in figures circles = 23
Therefore, required number of cars having none of the options = 25 - 23 = 2.
