Question

You survey 100 customers. You ask a question with 4 possible responses. Each possible response is given by at least 10 customers. What is the maximum number of customers giving any one response

Answer 1

Total Number of customer who underwent Survey=100

Number of Possible Answer of each Question=4

Suppose Four Response of a Question are , A , B ,C and D.

→Number of Customers whose answer is A ≥10

→Number of Customers whose answer is B ≥10

→Number of Customers whose answer is C ≥10

→Number of Customers whose answer is D ≥10

All Customers whose answers are ,A, B, C and D are Real Multiple of 10.

So,In Terms of equation it, can be written as

⇒10 x+10x+10x+10x=100

40 x=100

Dividing both side by 40 , we get

x=2.5

⇒Maximum number of customers giving any one response, that is Either A, B,C or D will be

=10×2.5

=25 Customer
