Since we have given that
Total amount of solution = 40 ml
One- quarter of the solution is given by

Three-quarter of the solution is given by

According to question, we have
10 ml of solution is made up of = 20% of acid solution
30 ml of solution is made up of = say<em> 'c </em>' of acid solution
40 ml of solution is made up of = 32 % of acid solution
So, our equation becomes,

Hence, three quarters (30 ml) is made up of a 36% acid solution.
