A frock is listed at 220 and a discount of 20% is announced. Its sale price is:
A44
B180
C200
D176
Answer & Solution
Correct answer: D. 176
1. The list price is the same as the marked price, so the base is 220.
2. A discount of 20 per cent means 20 off every 100.
3. The discount is therefore 20 / 100 x 220 = 44.
4. The sale price is 220 - 44 = 176.
5. Answering 44 gives the discount rather than the price actually paid.
