There are 2 jars. One jar with the capacity of 5 ltrs and another with a capacity of 3 ltrs. You should fill 4ltrs of water using both of these jars, there's no measuring instrument available to measure. how will you fill 4 ltrs of water?

• 1. fill the 3 lts jar
  2. pour this into the 5 ltrs jar
  3.repeat the process and now 5 lts jar will be full and 3 lts jar will have 1 ltr left in it... 3+3-5=1
  4. empty the 5 ltr jar...although it is not good to waste water
  5. pour the 1 ltr water left in the 3 ltr jar into the 5 ltr jar
  6. fill the 3 ltr jar again and pour it into the 4 ltr jar so you will have 1+3=4 ltr water exactly.

• 1.Fill 5L jar
  2.transfer it to 3L jar, now you're left with 2 liters in 5L jar.
  3.empty 3L jar.
  4. transfer the 2 liters balance in 5L jar to 3L jar.
  5. so now we have an empty 5L jar and 2liters filled 3L jar.
  6. fill 5L jar.
  7.3L jar has 2 liters already so it can only accomodate 1liter more, so transfer 5L jar water to 3L, untill it gets full.
  8.so now we 4 liters(5-1) in 5L jar.

• Let us take the jar to be filled with 4 ltrs of water as "A jar"
  Step 1: Take water in 3 ltr jar and pour in the A jar... Now, A jar has 3 ltrs of water.
  Step 2: Again take water in 3 ltr jar and pour in 5 ltr jar.
  Step 3: Repeat the Step 2.
  Step 4: Now, you have remaining 1 ltr of water in 3 ltr jar. Pour the remaining water in the A jar.
  As a result, A jar has 4 ltr water, as we expected...

• Totally 5+3=8
  8/2=4
  therefore mix the waters of both the jar into a single one and pour half of the content into another which makes
  4 litres each simple.

• Initially fill the 3 litre jar and pour it completely in the 5 litre jar. Hence the 5 ltrs jar contains 3 ltrs of water and the other jar is empty. Now fill the 3 ltr jar completely again and pour it into the 5 ltr jar upto the brim and hence the 3 ltr jar now contains only 1 ltr as the 2 ltrs of water is poured into the 5 ltr jar. Drain out the 5 ltr jar completely and transfer the 1 ltr from the 3 ltr jar into the 5 ltr jar. Fill the 3 ltr jar again and pour it completely into 5 ltr jar. Thus the 5 ltr jar now contains 4 ltrs of water.

• Initially the jars are empty.
  Let jar A and B be of capacities 5l and 3l respectively.
  Fill the jar B with 3l of water and completely pour it in jar A. (Jar A: 3l, Jar B: 0l)
  Fill the jar B with 3l of water and pour it in jar B until it is full, (Jar A: 5l, Jar B: 1l)
  Empty jar A.(Jar A: 0l, Jar B: 1l)
  Pour water from Jar B to A.(Jar A: 1l, Jar B: 0l)
  Fill the jar B and transfer it to jar A.(Jar A: 4l, Jar B:0l)
  Hence 4l of water is filled in Jar A.

• The solution is very simple .
  fill both the jars full of water. Start tilting the jars till the water level reaches both of the diagonal ends on top as well as bottom i.e. half of the quantity which means 5/2=2.5 and 3/2=1.5 ... add both of them 2.5+111.5=4.

• lets name 5lts jar as A and 3ltrs jar as B
  first fill A=5 and B=0
  A is full B is empty
  now pour some water from A to B till B gets filled now, A=2, B=3
  empty B,now A=2,B=0
  pour the water from A to B
  now, A=0,B=2
  fill A fully again so,A=5,B=2
  pour water from A to B until B is full
  A=4,B=3
  now empty B
  thus, A=4,B=0
