Question

A solution contain 10 percent of sugar one fourth of the solution was replaced by a second solution which results in a solution that contain 60 percentage of sugar

Answer 1

Answer:

The allegation formula is this:

w1/w2 = (A2 - Aavg)/(Aavg - A1)

w1/w2 is the ratio of weights of the two solutions. Here, since 1/4 of the first solution is replaced, the weight of the first solution is 3/4 and that of the second solution is 1/4 so w1/w2 = 3/1

A2 - Concentration of second solution which we have to find here

Aavg - Concentration of mixture which is 16%

A1 - Concentration of first solution which is 10%

3/1 = (A2 - 16)/(16 - 10)

A2 = 34%
