Answer:
10 litres of 1% solution and 8 litres of 10% solution
Step-by-step explanation:
Let vol of 1% solution = x
So vol of 10% solution = 18 - x
5% of 18 litres = 0.9
Equation formed is
<h3>x * (1/100) + (18 - x)*(10/100) = 0.9</h3>
x + (18 - x)10 = 0.9 * 100
x + 180 - 10x = 90
-9x = 90 - 180
-9x = -90
x = 10 litres
<h3>10 litres of 1% solution and 8 litres of 10%</h3>
