Answer 2

Answer:

48 hours

Step-by-step explanation:

since, part of tank filled by Pipe in 12hrs = 1

so, part of tank filled by Pipe in 1 hr = $\frac{1}{12}$

Given that, Tank is filled in 16hrs when a waste pipe is opened which empties a tank.

Let us take "x" as the time taken by waste pipe to empty the tank.

so part of tank emptied by waste pipe = $\frac{1}{x}$

we can write it in this way :

$\frac{1}{12} - \frac{1}{x} = \frac{1}{16}$

$= > \frac{1}{x} = \frac{1}{12} - \frac{1}{16}$

taking LCM (12,16) we get 48 .

$= > \frac{1}{x} = \frac{4 - 3}{48}$

$= > \frac{1}{x} = \frac{1}{48}$

$= > x = 48 \: hrs$
