How many liters of pure water must be added to how many liters of a 25% bleach solution to make 12 liters of a 15% bleach soluti

ArbitrLikvidat [17]

Answer: 4.8 liters

Step-by-step explanation:

Let x liter of water is added with y liter of 25% beach solution.

Thus, According to the question,

x + y = 12 -------(1)

0% of x + 25 % of y = 15 % of 12

25 % of y = 15% of 12

$25 y = 15\times 12$

$y = \frac{180}{25}$

$y = \frac{36}{5}$

Put this value in equation (1),

We get,

$x + \frac{36}{5} = 12$

$x = 12-\frac{36}{5}$

$x =\frac{60-36}{5}$

$x =\frac{24}{5}$

Therefore, the quantity of water = $x =\frac{24}{5}=4.8\text{ liter}$

And, the quantity of 25% bleach solution = $y =\frac{36}{5}=7.2\text{ liter}$

The formula of a midpoint of the segment between the points

$(x_1,\ y_1),\ (x_2,\ y_2)\\\\M\left(\dfrac{x_1+x_2}{2},\ \dfrac{y_1+y_2}{2}\right)$

We have:

$(17,\ -11),\ (-14,\ -16)$

Substitute:

$M\left(\dfrac{17+(-14)}{2},\ \dfrac{-11+(-16)}{2}\right)\to M\left(\dfrac{3}{2},\ \dfrac{-27}{2}\right)$
