In 1995 Division A of Company X had 4850 customers. If there were 85 service errors in Division A that year, what was the service-error rate, in number of service errors per
100 customers, for Division B of Company X in 1995?
1, In 1995 the overall service-error rate for Divisions A and B combined was 1.5 service errors per 100 customer.
2, In 1995 Division B had 9350 customers, none of whom were customers of Division A.
Combined Service Error rate=1.5 but no mention of total number of Customers or the number of customer in Div B. Insufficient.
No. of Customers=9350 in Div B but no mention of Service errors so not possible to find no. of errors per 100 customers. Insufficient.
Combining Both the statements,
Total no. of customers=9350+4850=14200
Service error/100 customer= 1.5
Total no. of service error=1.5*14200/100
Service error in B=213-86=127
service error/100 customer in B = (127/9350) *100
