MATH : PIPE AND CISTERNS PROBLEM, UNIT-1
1. Pipes A and B fill tank in 24 and
30hrs. How much time the will tank if they both started together?
2.
Pipe A fill tank in 15hr. Due to leak, it fills in 20hr. If tank is full, how much
time it will take to empty it ?
3. Pipe A and B fill tank in 6 and
9hr and pipe C take 12hr to empty it. If they started together. Tank will fill
in?
4.
Two pipe A and B fill tank in 24 and 32min. If both pipes are opened together,
after how much time should B be closed so that tank fill in 18min?
5.
Pipes A and B can fill a tank in 5hr and 6 hours respectively. Pipe C can empty
it in 12 hours. If
all the three pipes are opened
together, then the tank will be filled in?
6.
A pump can fill a tank with water in 2 hours. Because of a leak, it took 2+1/3
hours to fill the
tank. The leak can drain all the
water of the tank in how much time?
7.
Two pipes A and B can fill a cistern in 37+1/2 minutes and 45 minutes
respectively. Both pipes are opened. The cistern will be filled in just half an
hour, if the B is turned off after how much time?
8.
A tank is filled by three pipes with uniform flow. The first two pipes
operating simultaneously fill the tank in the same time during which the tank
is filled by the third pipe alone. The second pipe fills the tank 5 hours
faster than the first pipe and 4hrs slower than 3rd pipe. the time required
by first pipe is?
9.Two
pipes can fill a tank in 20min and 24minutes respectively and a waste pipe can
empty 3
gallons
per minute. All the three pipes working together can fill the tank in 15
minutes. The
capacity of the tank is?
10.
A tank is filled in 5 hours by three pipes A, Band C. The pipe C is twice as
fast as B and B is
twice as fast as A. How much time
will pipe A alone take to fill the tank?
11.
Two pipes A and B together can fill a cistern in 4 hours. Had they been opened
separately, then B would have taken 6hours more than A to fill the cistern. How
much time will be taken by A to fill the cistern separately?
12.Two
pipes A and B can fill a tank in 20 and 30 minutes respectively. If both the
pipes are used together, then how long will it take to fill the tank?
13.Two
pipes A and B can fill a tank in 15 minutes and 20 minutes respectively. Both
the pipes are opened together but after 4 minutes, pipe A is turned off. What
is the total time required to fill the tank?
14.
One pipe can fill a tank three times as fast as another pipe. If together the
two pipes can fill the tank in 36 minutes, then the slower pipe alone will be
able to fill the tank in?
15.
A large tanker can be filled by two pipes Aand B in 60 minutes and 40 minutes
respectively. How many minutes will it take to fill the tanker from empty state
if B isused for half the time and A and B fill it together for the other half?
16. A tap can fill a tank in 6
hours. After half the tank is filled, three more similar taps are opened. What
is the total time taken to fill the tank completely?
17.Three
taps A, B and C can fill a tank in 12, 15and 20 hours respectively. If A is
open all the time and B and C are open for one hour each alternately, the tank
will be full in?
18.
Three pipes A, B and C can fill a tank in 6hours. After working together for
2hours, C is closed and A and B can fill the remaining part in 7 hours. The
number of hours taken by C alone to fill the tank is?
19.Pipe
A and B can fill tank in 20min and 60min. Both are opened 10min then A is off. After, how much time tank
will be filled?
20.
pipe A and B fil tank in 20hr and 30hr. if anther pipe B empty it in 40hr. then
in how much time tank will be filled if C is opened after 3hr?

|
Find The least number which
is divisible by x, y, z gives
reminders ‘r’
|
Required number =
LCM of (x, y, z)+r
|
|
|
Find The least number which
is divisible by x, y, z gives same
reminders

|
Find the n digits Greatest
number which is divisible by x, y, z
|
LCM of x, y, z =L
Divide the n-digits greatest
number by L and reminder R
Leaves No Reminder then:
N digit number – R
Leaves reminder K in each case
[n digit number –R] + k
|
|
|
Find the n digits Smallest
number which is divisible by x, y, z
|
LCM of x, y, z =L
Divide the n-digits greatest
number by L and reminder R
Leaves No Reminder then:
Required number: n digit
smallest number + (L-R)
Leaves reminder K in each case
Required number: n digit
smallest number+(L-R)+K

Mathematics Basic concepts : Unit-I
Test of divisibility:
A number is divisible by ‘2’ if it ends in zero
or in a digit which is a multiple of ‘2’i.e.
2,4, 6, 8.
A number is divisible by ‘3’, if the sum of the
digits is divisible by ‘3’.
A number is divisible by ‘4’ if the number formed
by the last two digits, i.e. tens and
units are divisible by 4.
A number is divisible by ‘5’ if it ends in zero
or 5
A number is divisible by ‘6’ if it divisible by
‘2’ as well as by ‘3’.
A number is divisible by ‘8’ if the number formed
by the last three digits, i.e, hundreds
tens and units is divisible by ‘8’.
A number is divisible by ‘9’ if the sum of its
digit is divisible by ‘9’
A number is divisible by ‘10’ if it ends in zero.
A number is divisible by ‘11’ if the difference
between the sums of the digits in the
even and odd places is zero or a multiple of ‘11’.
LCM:
LCM of
a given set of numbers is the least number which is exactly divisible by
every number of the given set.
HCF:
HCF of
a given set of numbers is the highest number which divides exactly every
number of the given set.
Additional Rules
The square of an odd number is always odd.
A number is said to be a prime number if it is
divisible only by itself and unity. Ex. 1,
2, 3, 5,7,11,13 etc.
The sum of two odd number is always even.
