B) Rs. 5.68
C) Rs. 5.82
D) Rs. 5.58
E) None of these
Correct Answer: E
Solution :
| Total cost price of jowar \[=170\times 5.8=Rs.\,986\] |
| Total cost price of another type of jowar |
| \[=130\times 5.30=689\] |
| Total cost price \[=689+986=1675\] |
| Total profit \[=1.61\times (170+130)\] |
| \[=1.61\times 300=483\] |
| Selling price = Cost price + Profit |
| \[=1675+483=2158\] |
| Selling price per kg \[=\frac{2158}{300}=Rs.\,7.19\] |
