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.

Hi All,

We're told that the normal price of a dress is D, but when on sale has its price reduced by 15% and the staff are allowed a further 10% reduction on the discounted price. We're asked for a staff member's price in terms of D. This question can be solved by TESTing VALUES.

IF....
D=$100
The discounted price = $100 - (.15)($100) = $100 - $15 = $85
The staff price = $85 - (.1)($85) = $85 - $8.50 = $76.50

Thus, the staff's price is (76.50/100)(D) = 0.765D

Final Answer: C

GMAT assassins aren't born, they're made,

The staff member pays D x 0.85 x 0.9 = 0.765D.

Answer: C
