Answer 1

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

Cost of 1000 Articles = 5000, cost of one article = 5000/1000=5

Cost of 1000 Articles = 4000, cost of one article =4000/1000=4

Decrease in price = Rs. 5 – Rs. 4 = Rs. 1

Decrease of % = 1/5 * 100 = 20%

Answer 2

Dear Student,

Solution:
➖➖➖
A.T.Q. Last Cost of 1000 articles = 5000 Rs.

This year cost of 1000 articles = 4000 Rs.

Total decrease = 5000-4000 Rs.

Total Decrease = 1000 Rs.

Decrease percentage =
$\frac{1000}{5000} \times 100 \\ \\ = \frac{100}{5} \\ = 20$


Total decrease in cost is 20%.

Hope it helps you.
