A dress on sale in a shop is marked at SD. During the discount sale, its price is reduced by 15%. Staff are allowed a further 10% reduction on the discounted price. If a staff member buys the dress what will she have to pay in terms of D?
A. 0.75D
B. 0.76D
C. 0.765D
D. 0.775D
E. 0.805D
The OA is C.
Successive discounts = -a - b + ab/100
Putting the values,
Total discount = -15 - 10 + 150/100 = -25 + 1.5 = 23.5% discount.
Hence the final price of the dress = D - 0.235D = 0.765D. Option C.
