1) In the middle of water pool their is beautiful water Lily . The lily doubles in its size each day and it becomes exactly equal to size of pool in 20 days ?
How many days will it take to grow equal to half of water pool.

Ans :
Size of lily * 2^20 = Size of pool
Size of lily * 2^x = Half Size of Pool
Solve this you will get x=19 days.

2) In party every guest shakes hand with every other. If there are 66 hand shakes then how many peoples/guest are present at party.

Ans :

 Container A Container B
  (5 litre )    (3 litre )

1.   5 lt.   0 lt.  //pour 5 litre in A container
2.  2 lt.    3 lt.  // insert 3lt. in B
3.  2 lt.    0 lt.  // empty B
4.  0 lt.    2 lt.  //pour 2 lt. from A -> B
5.  5 lt.    2 lt.  // Fill A fully i.e. 5 litres
6.  4 lt.    3 lt.  // We can only pour 1 litre in B to fully fill it.
