Question
Solution A contains 10% acid and solution B contains
30% acid. In what ratio should solution A be mixed with Solution B to obtain a mixture with 25% acid?Solution
In solution 1 acid percent=10 In solution 2 acid percent=30 In the resulting mixture acid percent=25% By applying the principle of allegations we have =(30-25)/(25-10) =5/15 =1:3
