Question 9

KBC restaurant chain regularly conducts survey of its customers. The customers are asked to rate the food quality, service and price as Excellent, Good and Fair. Customers are also asked whether they would comeback. It was found that 76% of customers say that they will come back. Amongst those who say that they will come back, 57% rate the restaurant as Excellent, 36% rate it as Good and remainder rate it as Fair. Of those who say that they will not return, the respective values are 14%, 32% and 54%. What percentage of customers rated the restaurant as good ?

Solution

Let the total customers be 100.

Number of customers who said that they will return = 76x

Number of customers who said that will not return = 24x

Number of customers among those who said that they will return rated the restaurant as good = 76x*0.36

Number of customers among those who said that they will not return rated the restaurant as good = 24x*0.32

Number of customers who rated the restaurant as good = 76x*0.36+24x*0.32 = 35.04x

Percentage of customers who rated the restaurant as good = approx 35%

B is the correct answer.
