A shop offers a 20% discount. The sale price of a bag marked at 250 is:
A180
B210
C230
D200
Answer & Solution
Correct answer: D. 200
1. A 20 per cent discount means the customer pays 80 per cent of the marked price.
2. The marked price here is 250.
3. So the sale price is 80 / 100 x 250.
4. That is 200.
5. Checking the other way, the discount is 20 / 100 x 250 = 50, and 250 - 50 = 200.
