1.	The list price of an AC is Rs. 20,000. The shopkeeper sold it by allowing a 4% discount and charged 5% sales tax. By mistake , while calculating the bill, he considered 5% discount and 4% sales tax. As a result, the customer must have paid ____.A. Rs. 200 lessB. Rs. 400 lessC. Rs. 400 moreD. Rs. 200 more
Answer» Correct Answer - B List price = Rs. 20,000 Discount (in Rs.) `=(4)/(100)(20,000)=800` Price after discount = Rs. 19,200 Sales tax (in Rs.) `=(5)/(100)(19,200)=960` Amount to be paid (in Rs.) =19,200+960=20,160 Discount calculated (in Rs.) `=(5)/(100)(20,000)=1000` Calculated price after discount =Rs. 19,000 Sales tax calculated (in Rs.) `=(4)/(100)(19,000)` =760 Amount actually paid (in Rs.) =19,000+760=19,760 `therefore` The customer must have paid (20,160-17,760), i.e., Rs. 400 less.
