D) 25%

Explanation:

Productivity can be described as a measure of profitability of the work done by a company. For example a sales department may measure productivity by number of closed sales in a week.

In this instance the cleaning company will consider cost reduction an increase in productivity.

They were using 10 lbs each for house A, B, and C (30 lbs). An additional 10 lb is used increasing total chemicals used to 40 lb.

The increase in chemical usage is a drop in productivity for the company as they are spending more.

The percentage drop in productivity is a proportion of the additional quantity of chemical to total chemicals used.

Percentage drop in productivity = (10/40) * 100 = 25%
