### What is Outlet?

**Outlet:** A Pipe linked with tank it vacant is called as an outlet. A pipe can vacant a tank means nature of pipe is minus.

### Formulas of Pipe and Cistern

- If a pipe can fill a tank in X hours, then, part filled by 1 hours =
**1 / X**.

- If a pipe can vacant a tank in Y hours, then, part emptied in 1 hours =
**1 / Y**.

- The next one is, If a pipe can fill a tank in X hours and another pipe can vacant the full tank in Y hours ( where X>Y ), then on opening both the pipes, the net part filled in 1 hours =
**(1 / X) – (1 / Y).**

- And lastly, If a pipe can fill a tank in X hours and another pipe can empty the full tank in Y hours ( where Y>X ), then on opening both the pipes, the net part emptied in 1 hours =
**(1 / Y) – (1 / X).**

Twp pipes A& B fill a tank in 20 min & 30 mins respectively and pipe C empty the tank in 15 mins.if all pipes are opened successively then in what time tank will completely filled..??

According to formula..

-mnp/m×n+(-n×p)+(-p×m)

-20×30×15/20×30-30×15-15×20

=-9000/600-450-300

=-9000/600-150

=-9000/500

=18min.

60 minutes

It will not fill at any more..

60 minutes will be required to fill ups the tank.

1/20+1/30-1/15

=>1/60

60mints

Vol. =lcm(20,30,15)=60

A can fill/min.=3unit

B can fill /min=2unit

Total fill/min=5unit

C can empty the tank/min=4unit(60/44

So total fill /min=5-4=1unit

So total time taken to fill the tank=60 min or 1h

(1/20+1/30)-1/15=1/60

60min

take LCM = 3+2-4/60 = 1/60 ONE MIN , 60 MIN IS REQUIRED TO FILL THE TANK.

Let Capacity =60L

Rate of A=3L/M

Rate of B= 2L/M

Rate of C=4L/M

Net inflow=1L/M

For 60L it’s 60M assuming all pipes are open simultaneously

1/20+1/30-1/15

LCM of 20,30,15 is60

3+2-4/60=x

X=60minutes

X= 1 hour

1/20+1/30-1/15 = 1/60

Hence 60/1 mins.

60 mins

60 mins

60 mins

60mins will be required to fill up the tank or 1hour

60

167 minutes

can u explain the same using lcm method

X=20,Y=30,Z=15

THIS IS FORMULA 1/X+1/Y-1/Z

IF WE USE LCM METHOD FORMULA WILL BE IN THIS FORM,

X*Y*Z/ Y*Z+Z*X-Y*X

=20*30*15/30*15+20*15-30*20

=9000/450+300-600

=9000/150

=900/15

=60 MINS

60 min is required to fill the tank
