Cost price = Rs. 1280 for 16 quintals
Quantity of rice with the trader after transportation lost = $\frac{100-18}{100}\times 16=\frac{82}{25}\times 4$
= 13.12 quintals
To have 23% profit, total selling price of the trader should be = $\frac{123}{100}\times 1280$
= Rs. 1574.4
∴ Selling price per quintal = $\frac{1574.4}{13.12}=$ Rs.120
