by Emmanuel Atoyebi
Product Brand Analysis A company produces brand A, B and C of cement. 250 customers liked brand A. 248 Customers liked brand B. 100 Customers liked A only. 50 customers liked A and B but not C. 128 customers liked C but disliked A or B. 65 customers liked A and C but not B. 17 customers liked none of the brands. Determine the number of customers that liked all three brands. Determine the number of customers that liked B and C only. Determine the number of customers that were not interviewed.
