So in this question we are given two families.
00:08
Let's call first family as family one and the second family as f2.
00:16
So the output of the sprinkler used by family one.
00:24
Let's denote it with of1.
00:27
So this is 20 litre per hour and the output of sprinkler used by family 2, of2, is 15 liter per hour.
00:43
So let t1, t2 denote the times sprinkler used by family 1 and family 2 respectively.
01:02
That means t1 is the time of the sprinkler of family 1 and t2 is the time of the sprinkler of family 2.
01:09
And this is given to us in the question that the sprinklers together were used for 35 hours.
01:19
And we are also given that total output of both the sprinklers is 625 liters.
01:30
So let's see how to interpret this information.
01:34
So total output will be computed by the total amount of time, multiplied by the output per unit time of each sprinkler.
01:44
So this is the total output means output of sprinkler 1 and output of sprinkler 2...
