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 |

@Kartik.
(41+29+10)% = 80%
Fail and pass percentage is 20 yes.
(41+29+10)% = 80%

Can we do it by allegation?

I think by allocation we can find ratio problems only.

Friends the total kgs are only 56. Because 36 is the rate of 30 kgs.

What if we do it with LCM method?

How S.P is 56*30?

Could some one derive the formula or explain the following formula:
If two similar articles are sold, one at a gain of A% and another at a loss of A%, then always loss is incurred and loss percent = (A*A)/100%.
If two similar articles are sold, one at a gain of A% and another at a loss of A%, then always loss is incurred and loss percent = (A*A)/100%.

Can we apply allegation concept in this question?

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.
