 This presentation deals with solving problems on mixtures and solutions.
 The technique of reducing it to a simple algebraic problem is illustrated.
Question 1
A is 20% water and 80% milk. B is 5 % water and 95% milk. What ratio should they be
combined to get a mixture which is 10% water.
We want a mixture which is 10 % water
Question 2
2 brands of detergent are to be combined. Detergent A contains 20% bleach and 80%
soap while detergent B contains 45% bleach and 55% soap. If the combined mixture is
35% bleach what is the % of A in the final mixture?
Combined mixture is 35 % bleach
Question 3
How many litres of 20% alcohol solution should be added to 40 litres of a 50% alcohol
solution to make a 30% alcohol solution.
The resultant solution should be30% alcohol
Question 4
A 50 ml aftershave lotion at 30% alcohol is mixed with 30ml of pure water. What is the
% of alcohol in the new solution.
The original solution has 30 % alcohol
Question 5
200 litres mixture is 90% water and 10% salts. How much water should be added to
get a mixture which is 5% salts.
The new mixture has 5 % salts
Question 6
A mixture of 12 gms of vinegar and oil is 40% vinegar. How many gms of oil must be
added to the mixture to produce a mixture that is 25% vinegar
The new mixture is 25 % vinegar
 I hope this was useful to students trying to solve problems involving mixtures.
