Question

Price of an article is first increased by 40% and then reduced by 20%. What is the percentage increase in its price

Answer 1

Let the original price be Rs. 100.
New final price = 120 % of (75 % of Rs. 100) = Rs. (120/100 * 75/100 * 100) = Rs. 90.
Decrease = 10%
Do ur sum in this method

Answer 2

Answer:

Increase Percentage = 12%

Step-by-step explanation:

Let the price of an article be $100

Price Increased by 40%

So, Increased Price = 100 + 40% of 100

= 100 + ( 0.4 × 100 )

= 100 + 40 = $140

Now, this obtained price is decreased by 20%

= 140 - 20% of 140

= 140 - ( 0.2 × 140 )

= 140 - 28 = $112

Now, net increase in price of the article = 112 - 100 = $12

$\text{Percentage Increase in the price = }\frac{\text{net increase}}{\text{Original Price}}\times 100\\\\= \frac{12}{100}\times 100 = 12\%$

Hence, the percentage increase in the price of article  = 12%
