Question

an outlet empties 3/8 of the tank in 12 minutes. to empty the remaining content it should further take

Answer 1

Answer : Time taken to empty the remaining content of the tank is 20 minutes.

Explanation:

Since we have given that

An outlet empties 3/8 of the tank in 12 minutes.

By using unitary method, we can find whole tank empties in how much time i.e.

$\frac{3}{8}\times x=12\\\\x=\frac{12\times 8}{3}\\\\x=32\text{ minutes }$

So, we need to find the time required to empty the remaining content,

Remaining content is given by

$1-\frac{3}{8}$

$=\frac{8-3}{8}$

$=\frac{5}{8}$

So, Time required to empty the remaining content is given by

$\frac{5}{8}\times 32\\\\=\frac{5\times 32}{8}\\\\=20\text{ minutes }$
