Question

Jen wants to make 60% salt solution using 18g of salt. How much water should she use?

Answer 1

12g of water I think would be the correct answer

Answer 2

12 g of water she use.

Explanation:

Given : Jen wants to make 60% salt solution using 18g of salt.

To find : How much water should she use.

Solution : Let x be the solution.

So, 60% of x is 18 g.

∴
`(60)/(100)* x = 18`

`x = (18* 100)/(60)`

`x = 30`

Which means Total solution is 30 g and 18 g is the salt

So, quantity of water = 30-18 = 12g
