Question

Last year the cost of 1000 articles was ₹5000. This year it goes down to ₹4000. what is the percentage of decrease in price?​

Answer 1

Answer:

20 %

Step-by-step explanation:

Cost of 1000 articles last year= Rs.5000

Cost of 1000 articles this year= Rs. 4000

Decrease in price= Rs 5000 - Rs 4000= Rs 1000

Percentage of Decrease= Decrease Amount/ Initial Cost * 100

                                        = 1000/5000 * 100

                                        = 1/5 * 100

                                        = 20%

Answer 2

Before, finding the answer. Let's find out how we can find the answer.

• Here, in this question, we are asked to find the Decreased Percent.
• So, to find the Decrease percent, we must first subtract the cost of the article in the last year from the cost of the article this year.
• Next, we must use the formula of :

$\boxed{ \tt Decreased \: Percent = \frac{decrease \: amount }{original \: amount} \times 100}$

Given :

• Cost of Article last year = Rs. 5000
• Cost of Article this year = Rs. 4000

To find :

• percentage of decrease

Solution :

Decrease Amount = Rs. 5000 - 4000

                              = Rs. 1000

${ \tt Decreased \: Percent = \dfrac{decrease \: amount }{original \: amount} \times 100}$

                               $\tt = \dfrac{100 }{5000} \times 100}$

                               $\tt = \dfrac{10000 }{5000}$

                               $\tt =20$

Therefore, the decrease percent is 20%.
