Acompany employs 400 salespeople. of these, 83 received a bonus last year, 100 attended a special sales training program at the beginning of last year, and 42 both attended the special sales training program and received a bonus. (note: the bonus was based totally on sales performance.)
d) what proportion of the salespeople who attended the special sales training program received a bonus?

21/50

Step-by-step explanation:

Total Number of salespeople in company = 400

Of these salespeople, number of people recieved bonus last year = 83

Number of salesperson attended special sales training = 100

And, Number of salesperson attended both special sales training and received a bonus = 42

Then proportion of salesperson who attended special sales training program and received bonus = Number of salesperson attended both special sales program and received a bonus / total number of salesperson attended special sales training

                                   =  42/100

                                  = 21/50
