Question 56

If a shopkeeper gives two successive discounts of 20% and 15% on a book whose marked price is Rs. 850, then what is the selling price of the book?

Solution

The shopkeeper gives two successive discounts of 20% and 15% on a book whose marked price is Rs. 850.

Total discount $$=20+15- \frac{20\times15}{100} = 32$$

Selling Price $$=\frac{68}{100}\times 850 = Rs. 578 [SP=\%discount\times MP]$$

Option D is correct.
