Details of Allegations and Mixtures Problem Solutions:
Suppose you are given a question like the one given below:
Question: In a 60 liters mixture of milk and water, the quantity of milk is 5 %. In how much quantity, should milk be added to this mixture so that the quantity of milk in the mixture becomes 15 % ?
Answer: Now in this question, we have to add the milk to the solution in that quantity so that the quantity of milk in the mixture get to be 15 %.
Here is a shortcut formula for this type of questions. Just follow the rule given below for this type of question and remember the formula.
Rule: In x gram mixture of milk and water, milk is p %. To make the quantity of milk in the mixture to be q %, the quantity of milk added to the mixture will be =x{(q-p)/(100-q)}
Now let us solve the question given above as per this rule:
Here in this question:
X= 60 liters,         p= 5 %,                 q= 15 %
The quantity of milk to be added  to the mixture to make it 15 % in mixture-
                =120/17 liters     answer
Similar opposite question to the above is here. In this question the formula is slightly changed.
Rule 2: in x gram mixture of milk and water, there is p % water. To make the quantity of water to be q % , the quantity of water to be converted into steam will  be
Question based on rule 2:
In 750 gram of mixture of salt and water, there is 30 % water. How much water should be converted to steam so that water in the mixture remains 25 %.
Here in this question,
                X=750 gram,       p= 30 %,               q= 25 %
Now putting the formula given in Rule 2:
                The quantity of water which should be converted to steam will be
                = 750*{(30-25)/(100-25)                grams
                =750*(5/75)       grams
                = 50 grams

So 50 grams of water should be converted to steam to make the mixture having the quantity of water 25 % remaining.

Good Luck
