Question

The price of a TV is increased by 20 %. By what percent must it be decreased to bring it back to the original price ? ​

Answer 1

Answer:

16.67 % (approx.)

Step-by-step explanation:

Let us take the cost price (C.P) to be 100/- . So,

Increased price = (20% of 100) + 100

= 20 + 100

= 120/-

To find by how much percentage it would be decreased by,

⇒ 120 - 100 = 20

⇒ 120 * x% = 20

⇒ 120 * x/100 = 20

⇒ x = (20 * 100)/120

⇒ x = 16.6666666667% ≈ 16.67%

Hence, the TV must be decreased by approximately 16.67% to bring it back to the original price.
