The answer is A. Decreased by 4%.

Explanation:

Calculations are as shown below:

In the year of 2011:

Modern Electronics working hour's per day = Number of workers x working time per day = 80 x 8 = 640 hours

Number of calculators Modern Electronics made per one working hour (that is, productivity) = 60,000 / 640 = 93.75 calculators.

In the year of 2012:

Modern Electronics working hour per day = Number of workers x working time per day = 85 x 10 = 850 hours

Number of calculators made per one working hour (that is, productivity) = 76,500 / 850 = 90.00 calculators.

Comparision of productivity in the year 2012 over the year 2011 = 90/93.75 - 1 = - 4%

Thus, productivity decrease 4% in the year 2012 in comparison to the year 2011.
