Question

A retailer agreed to take 5000 ball point pen . How ever he found that 12% are faulty . What was the percentage decrement.

Answer 1

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%
