Answer the next 5 questions based on the information given below.
A survey was conducted in a class to find out the preference of its students. A total of 230 students liked Cricket, 240 students liked Football, while 290 people liked playing Hockey. Among these, 128 students liked only Cricket and Football, 50 liked playing only cricket and Hockey, while 22 liked only Hockey and Football. There were 50 students who liked all three types of sport. A total of 500 students were surveyed.
From the given data, we get the following diagram.
Number of students who preferred only Cricket = 230 – (128 + 50 + 50) = 2.
Number of students who preferred only Football = 240 – (128 + 50 + 22) = 40.
Number of students who preferred only Hockey = 290 – (22 + 50 + 50) = 168.
∴ We get the following Venn Diagram.
∴ Number of students who preferred only cricket = 2
