A) 7%
B) 7.5%
C) 8%
D) 8.5%
Correct Answer: D
Solution :
List price of a video cassettes = Rs. 100 |
Let the rate of discount = r% |
Selling price of 3 video cassettes = Rs. 274.50 |
\[\therefore \] Selling price of 1 video cassette = Rs.\[\frac{274.50}{3}\] = Rs. 91.50 |
\[\therefore \] \[100-\frac{r}{100}\times 100\]= Rs. 91.50 |
\[100-91.50=r\]\[\Rightarrow \]\[8.50=r\] |
\[\Rightarrow \]Rate of discount = 8.5% |
