An office worker mails 25 envelopes to customers each day Ev

An office worker mails 25 envelopes to customers each day. Every envelope contains 3 reports with a paper clip on each one. The supply of paper clips is provided in boxes of 500. How many days will it take for the clerk to use up one box of paper clips?

Solution

Since an office worker mails 25 envelopes to customers each day and each envelope contains 3 reports, with a paper clip on each one, he/she uses up 25 * 3 = 75 paper clips in a single day.

Now, a box of paper clips contains 500 clips. Hence, the number of days required to use up one full box of paper clips = 500/75 = 6.67 = around 7 days..
