Question

Maya added 5 grams of salt into 20 grams of 50% salt solution. She made ___ grams of ___% salt solution.

Answer 1

25 grams of 57.75
Once added the solution is 25 grams total and the % is 57.75

Answer 2

She made 25 grams of 40% salt solution.

Explanation:

Given : Maya added 5 grams of salt into 20 grams of 50% salt solution. She made ___ grams of ___% salt solution.

To find : The blank space or she made how many grams of which % of the solution ?

Solution :

First we find the number of grams,

As the total weight of the solution which is derived from adding 5 grams into 20 grams is

T = 5 + 20 = 25 grams

Now, The % solution

It can be find by dividing the amount of salt initially by the total amount of the resulting solution multiplied by 100.

`C = (20* 0.5)/(25)*100`

`C = (10)/(25)*100`

`C = 10* 4`

`C =40\%`

Therefore, She made 25 grams of 40% salt solution.
