A trader mixes 26 kg of rice at Rs. 20 per kg with 30 kg of rice of other variety at Rs. 36 per kg and sells the mixture at Rs. 30 per kg. His profit percent is:
No profit, no loss
5%
8%
10%
None of these
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 = 80 x 100 % = 5%. 1600

Why we are computing answers in the whole mixture. Why there is a difference when we computed it in 1 kg per? Please explain.

The 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%.

@Mamta:

The addition should be 30+26=56 but not 36+26.

Total cp = 1600.
Total sp = 1680.
Profit = sp-cp.
Profit = 80.

1%of 1600 = 16
5% = 16*5 = 80.

80/56 * 56/1600* 100 = 5%.

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.

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%.
