A) 20%
B) 15%
C) 21%
D) 18%
Correct Answer: A
Solution :
| Let the cost price of the article be Rs. 100. |
| Then, printed price = Rs. 140 |
| and selling prices \[=100\times \frac{12}{100}+100\] |
| \[=100+12=Rs.\,\,112\] |
| Discount \[=140-112=28\] |
| Discount% \[=\frac{28}{140}\times 100=20\]% |
