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:
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 = |
 |
80 | x 100 |  % = 5%. |
| 1600 |

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%.
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%.

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

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.

Allegation concept would have been applicable if you wanted to know the ratio or the cost of the mixture. But here everything is given. This is a concept of weighted average. So in weighted average, the exact weights are not necessarily be taken.
Even the ratio of weights if taken will give the same result. Thus the weights 26 and 30 can be taken as 26:30 which is 13:15.
Thus they can be taken as 13 and 15 instead of 26 and 30. That will make the multiplication easy and the answer will be the same. As weighted average talks about the ratio of weights and not the exact weights.

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%.
