A defective briefcase costing Rs 800 is being sold at a loss of 8%. If the price isfurther reduced by 5%, find its selling price.

Given, cost price of the defective briefcase is = Rs. 800

The loss percent is = 8% of 100 = 8/100

Selling price of briefcase is = 800 - 800×8/100

= 800 – 64

= Rs 736

When the price is further reduced by 5% (Given) = 5% of 100 = 5/100

New selling price = 736 - 736×5/100

= 736 – 36.8

= Rs 699.2

∴ The selling price of the defective briefcase is Rs 699.2
