Calculate the receivable turnover ratio for the month of January. If the industry average of the receivable turnover ratio for the month of January is 5.2 times, is the company managing its inventory more or less efficiently than other companies in the same industry

The first part of the question is missing, so I searched for a similar one.  

accounts receivable turnover ratio = total sales on account / average accounts receivable

accounts receivable turnover ratio = $90,400 / $15,400 = 5.87

This ratio basically shows us how efficiently does a business collect its accounts receivables or debts from its customers. Usually this ratio is converted into days = 365 / 5.87 = 62 days. This means that on average, it takes the company 62 days to collect its debts.

The higher the ratio, the better. If the industry's average is 5.2, that means that this company is more efficient, i.e. collects its debt in a shorter time.
