L litre = S Sec
L/S litre = 1 Sec
L/S * 60 Litre = 1 min
L/S * 60 * 60 Litres = 1 hour
3600L/1000S Kilo Litres = 1 hour
3600LX/1000S Kilo Litres = X hours

1 hr= 60 min, 1 min=60 sec
Therefore 1 hr=60*60=3600 sec

Rate is L liters per S seconds
therefore Rate in liters per hour is 3600 L/hr
And finally Rate in kilo liters per hour is 3600 KL/1000 hr

Therefore in x hours, 3600xL/1000s blood will be pumped. hence Option A.

Kudos if it helps.

L litre = S seconds
In Xhrs there would 3600*X seconds

So volume pumped = 3600*X*L /S litres

In kilolitres 3,600LX/(1,000S)

L litres per S sec ---> L/S = 1 sec
1 hr = 3600sec
1 kilolitres = 1000L

In S Sec ---> L litres blood pumped
In X hours(3600S) ---> 3600LX blood pumped
In kilolitres ----> 3600LX/1000S

Option A

Let’s convert the rate to kiloliters per second.

L liters = L/1000 kiloleters. So, our new rate is:

(L/1000)/S = L/(1000S)

Now we need to determine how much blood is pumped in X hours, or 3600X seconds.

L/(1000S) * 3600X = 3600XL/(1000S)

Bunuel how would you solve this question?
Please explain in simplified form. This one is confusing.

1000 liters = 1 kiloliter, thus L liters = L/1,000 kiloliter

The rate of L liters per S seconds = \(Rate = \frac{Job \ done}{Time} = \frac{(\frac{L}{1,000})}{S}= \frac{L}{1,000S}\) liters per second.

Since, there are 3,600 seconds in one hour, then the rate in liters per hour would be \(\frac{3,600L}{1,000S}\) liters per hour.

\(Job \ done = Rate*Time = \frac{3,600L}{1,000S}*X = \frac{3,600LX}{1,000S}\).

Answer: A.
