You work for a carpet cleaning company. A potential customer asks how often they should have their carpet cleaned. He tells you that it is an office located on the fourteenth floor of a downtown high-rise. What do you recommend?

I would recommend to clean the carpet once in a day or two days one.

Explanation:

The company that is located on a high rise building have some advantages of having an environment that has a good breeze. This will make employees to work better as they feel better. But there are also many disadvantages associated with this. They may avoid small sand dust particles but larger particles get settled here.

Sand dust particles usually get settled at the ground level and at higher levels larger dust particles get settled. In the given scenario, the company is located at the 14th floor. Hence, as an employee, I would recommend to clean the carpet once in a day or once in two days for a clean and dust free work place.

Answer: D) every 6-12 months
