The marked price of an article is ₹50,000. Of three shopkeepers, the first one allows two successive discounts of 25% and 15%. The second one allows two successive discounts 20% and 20%. The third shopkeeper allows two successive discounts of 30% and 10%. From which shopkeeper does the customer get more profit ?

​Marked price (M.P.) = ₹50,000

Shopkeeper 1: Successive discounts of 25% and 15%

Shopkeeper 2: Successive discounts of 20% and 20%

Shopkeeper 3: Successive discounts of 30% and 10%

​$$=-x -y + \frac{xy}{100}$$ ​

​​Solution:

​
