Here, the point of this question is to apply volume-to-capacity (I don't know what it's actually called, sorry...) conversion formula.

As 1 m3 = 1000 litres

Then 180 m3 = (180 x 1000) litres = 180,000 litres

Now, water is pouring at the rate of 60 litres/min

=> It is pouring at the rate of 1 litre/sec

Therefore, the total time taken to fill the reservoir

= 180,000 secs

= 3000 mins

= 50 hrs

Hence, it will take 50 hours to fill the reservoir.

ristu: but answer is 30 hrs.

Creature101: How? If you are looking at Nitish's answer, it seems that he got the volume of the reservoir wrong. Do correct me if I'm wrong.

nitish0007: mene volume nhi nikali

Creature101: Sorry, don't understand Hindi.

nitish0007: I am not finding volume

Creature101: But you did divide volume (which you converted into litres) by rate of flow, getting the time in minutes. And it seems that you wrote the volume wrong by mistake (according to the question given, of course!), so...

Creature101: Hey, if my answer is wrong, it's wrong. But in the end, the person who asked the question shouldn't get the wrong answer. That's why I'm asking.
