Gala2k [10]

Answer:

"85.7%" is the right answer.

Step-by-step explanation:

According to the question,

The total capacity of water tank will be:

⇒ $v_1=A\times 14$

The total volume of water will be:

⇒ $v_2=A\times 12$

Now,

The percentage of total capacity will be:

= $\frac{100\times v_2}{v_1}$

= $\frac{v_2}{v_1}\times 100$

By putting the values, we get

= $\frac{A\times 12}{A\times 14}\times 100$

= $85.7$ %
