Answer:
a) true
Explanation:
2/10 net 30 means that if the costumer pays within 10 days, he will be offered 2% discount, otherwise the amount is due in 30 days in full.
DSO means average number of days the company takes to receive payment from customers of credit sales.
Since the DSO of a firm given is 28 days, which is lower than the 30 days credit period normally offered by the company, therefore it may indicate that the firm's credit department is operating effectively.
Hence, answer is a) true
