Given Cost of 1 quintal of rice = Rs. 250
Cost of 600 quintals of rice = 600 x 250 = Rs. 150000
Overhead expenses = Rs. 1000
CP = Rs. (150000 + 1000) = Rs. 151000
Profit % = (Profit/CP) x 100
7 = (Profit /151000) x 100
Profit = 1510 x 7
Profit = Rs. 10570
Now SP = CP + profit
= Rs. (151000 + 10570)
SP = Rs. 161570
