Answer: Option
Explanation:
C.P. of 56 kg rice = Rs. (26 x 20 + 30 x 36) = Rs. (520 + 1080) = Rs. 1600.
S.P. of 56 kg rice = Rs. (56 x 30) = Rs. 1680.
 Gain = |

For 1st type of rice :
Cost of 1kg of rice = Rs.20.
Cost of 26kg of rice = 20 * 26 = 520.
For 2nd type of rice:
Cost of 1kg of rice = Rs 36.
Cost of 30kg of rice = 36 * 30 =1080.
Total C.P = Rs.520 + Rs.1080 = Rs 1600.
Total rice weight (in kg) = 56.
So,
Trader sold this 56kg of rice @ Rs30/kg.
Total S.P = 56 * 30 = Rs. 1680.
Hence,
Gain = 1680 - 1600 = 80.
==> Gain% = (80/1600) * 100 = 5%.
Cost of 1kg of rice = Rs.20.
Cost of 26kg of rice = 20 * 26 = 520.
For 2nd type of rice:
Cost of 1kg of rice = Rs 36.
Cost of 30kg of rice = 36 * 30 =1080.
Total C.P = Rs.520 + Rs.1080 = Rs 1600.
Total rice weight (in kg) = 56.
So,
Trader sold this 56kg of rice @ Rs30/kg.
Total S.P = 56 * 30 = Rs. 1680.
Hence,
Gain = 1680 - 1600 = 80.
==> Gain% = (80/1600) * 100 = 5%.

Cost price of old mixture = (26 kg * rs.20) + (30 kg * 30) = 1600.
Cost of new mixture =( (26 kg + 30 kg) * rs. 30 ) =1680.
gain = 1680 -1600 = rs. 80,
gain percentage = ( 80 *100 )/1600 = 5%.
Cost of new mixture =( (26 kg + 30 kg) * rs. 30 ) =1680.
gain = 1680 -1600 = rs. 80,
gain percentage = ( 80 *100 )/1600 = 5%.

How 30 is multiplied with S.P?

Cp of 26kg is 20*26=520.
Then cp of 30kg is 30*36=1080.
Then total cp=1600(520+1080).
So=56*30=1680rs and difference is 80 is the profit. Then 80is 5% on cp.
Then cp of 30kg is 30*36=1080.
Then total cp=1600(520+1080).
So=56*30=1680rs and difference is 80 is the profit. Then 80is 5% on cp.
