Question

21. The price of an article was? 400. At first, the price increases by 20% and then it
decreases by 20%. Find the final price of the article and also express the net
increase or decrease as a percent.
​

Answer 1

Answer:

Let us assume the price of product be 100rs

increase in price is 20% hence new price is 20% of 100 =20 so new price would be 100+20=120.

Afterward there is a decrease of 30 % in price from 120 rs, hence 30% of 120 is 36 so new price would be 120–36 = 84.

So the overall %change is 16% as the initial price was 100 and new price is 84
