2. Answer:

   88%

   Step-by-step explanation:

   12% of pen is faulty.

   So, 12% of 5000 = 12 / 100 * 5000

   = 600

   600 pens are faulty

   Now remaining pens will be 5000 – 600 = 4400

   4400 pens are in good condition

   therefore, in %

   4400 / 5000 * 100 = 88%

   thus the pens’ value is reduced to 88%

   Quicker solution:

   Out of 100%, 12% were faulty.

   thus, % decrement = 100 – 12 = 88%
