Question

A big drum contains 58 litre 625 millilitre of water there is a small hole in its bottom from which 4 litre 225 millilitre of water flows out every hour how much water will be left in the drum after two hours​

Answer 1

Answer:

50 litre 175 milli litre

Step-by-step explanation:

4 litre 225 ml in 1hour

so in 2 hour 8 litre 450 ml will flow out

so remaining= (58-8) litre (625-450) ml

so answer 50 litre 175ml

Answer 2

Answer:

$50 l \:$ & $175ml$ of water will be left at the end of $2 hrs$

Explanation:

Given :

Initial volume of water stored in Drum : $58 l \:+ \: 625 ml$

Rate at which volume of water declines : $(4 l \: + \: 225 ml) / hr$

To Find :

To find the volume of water that remained after : $2hrs$

Solution :

Volume of water that drained out in given time =

$(4l + 225ml)/hr \times 2hr$

$= 8l + 450ml$

Now, Volume of water that wil be left after two hours =

$58 l + 625 ml - (8l + 450 ml)$

$=58l + 625ml - 8l - 450ml$

$= 50l + 175ml$
