Three quarters (30 ml) is made up of a 36% acid solution.
Step-by-step explanation:
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 'c ' 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.
