A) Rs. 5.50
B) Rs. 7.50
C) Rs. 10.50
D) Rs. 7.00
Correct Answer: D
Solution :
| [d] Reduction in price (P) = 21% |
| Total amount for purchase (y) = Rs. 100 |
| Amount of extra quantity that can be bought |
| \[(x)=3\,\,kg\] |
| \[\therefore \] Reduced price \[=\frac{1}{x}\left[ y+\frac{P}{100} \right]\] |
| \[=\frac{1}{3}\left[ 100+\frac{21}{100} \right]=\frac{21}{3}=Rs.\,\,7\] |
