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

Answer:

12 g of water she use.

Step-by-step 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.

∴  $\frac{60}{100}\times x = 18$

$x = \frac{18\times 100}{60}$

$x = 30$

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

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