Answer:

  • B) 28%

=================

Let the initial price be x.

After the first sales quarter the price is reduced by 10% and became:

  • x - 10% =
  • x - 0.1x =
  • 0.9x

After the second sales quarter the price is reduced by 20% and became:

  • 0.9x - 20% =
  • 0.9x - 0.2*0.9x =
  • 0.9x - 0.18x =
  • 0.72x

The decrease over the two quarters is:

  • x - 0.72x =
  • 0.28x

This is equivalent of 28%, hence the correct answer choice is B.
