A scientist has two solutions, which she has labeled Solution A and Solution B. Each contains salt. She knows that Solution A is
40
%

salt and Solution B is
65
%

salt. She wants to obtain
40

ounces of a mixture that is
60
%

salt. How many ounces of each solution should she use?

We need 8 ounces of solution A and 32 ounces of solution B.

Step-by-step explanation:

We are given that a scientist has two solutions, which she has labeled Solution A and Solution B. Each contains salt.

She knows that Solution A is  40%  salt and Solution B is 65%  salt.

                       A + B = 40

                        B = 40 - A  ------------ [Equation 1]

                            {from equation 1}

                                    A  =   = 8 ounces

Now, putting value of A in equation 1, we get;

                           B = 40 - A

                           B = 40 - 8 = 32 ounces

Hence, we need 8 ounces of solution A and 32 ounces of solution B.
