RIDDLES -- Dimag ki batti jalao

Sachin distributed mangoes between Saurav and Sandeep, cheating them of some and eating those himself. At the end of the distribution if Saurav were to give some mangoes to Sandeep, he would have 3 times as many mangoes as Sandeep. If sandeep were to give the same number of mangoes to Saurav, then Saurav would have 5 times the number of mangoes as Sandeep. If the total number of mangoes was thirty, then the number of mangoes eaten by Sachin are?

A king and his three sons

A King is dying. He has three sons. Sons have three horses. King has decided to organize a horse race and will give all of his property to the son whose horse is the last at the race. However, he wants race to be fair, meaning that he doesn't want sons to slow down their horses. What will he do?
 
Re:

If the property is to be given on the basis of the horses's ranks in the race, then the king could tell his sons to switch the horses, that is first son should participate in the race using his youngest brother's horse and in the same way, youngest son would have the middle son's horse; who would have the oldest son's horse for the race.

try one more Light swithes


Imagine, if you will, that you have a long, long corridor that stretches out as far as the eye can see. In that corridor, attached to the ceiling are lights that are switched ON and OFF by normal switch.
There are gazillions of them, as far as the eye can see. Let's say there are 50,000 lights in a row.
They're all off. Somebody (First person)comes along and swiched ON all the lights, turning on each one of the lights. Second person comes right behind, and change the postion of each switch which ser is divdable by two (all even nos). Thereby turning off lights 2, 4, 6, 8 and so on. Now, a third person comes along and change the postion of each switch on every third light. (divdable by three). That is, lights number 3, 6, 9, 12, 15, etcetera. Another person comes along and change the position on lights number 4, 8, 12, 16 and so on. Of course, each person is turning on some lights and turning other lights off.
If there are 50,000 lights, at some point someone is going to come skipping along and change 50,000th switch.
When that happens, some lights will be on, and some will be off. Can you predict which ones will be on?
 
Re:

:DLooks like an extension of One 100 door puzzle (most favorite of Adobe's interviewers).....Based on the toggling of the switches, the lights which are at the perfect square number will remain on ( means 1, 4, 9, 16, 25,..., 81.., so on...). Am I correct Sanjeev?

The owner of the mansion has been murdered! The visitors to the mansions were A, B, and C.

a) The murdered, who was one of the three visitor, arrived at the mansion later than at least one of the other two visitors.
b) A detective, who was one of the three visitors, arrived at the mansion earlier than at least one of the other two visitors.
c) The detective arrived at the mansion at midnight.
d) Neither A nor B arrived at the mansion after midnight.
5) The earlier arriver of B and C was not the detective
6) The later arriver of A and C was not the murderer.

Who was the murderer ?


Time limit = one and half minute (max.)
 
B

B is the murderer..........
am i right sir?

Ya Again correct Neetu, because only prefect squaare can have the odd nos of factors. (factors of all other nos will be in pairs) therefore only odd no of switching can lead to get it ON.
 
Re:

=> From (b) & (c), the detective arrived at midnight and at least one of the three visitors came after midnight.
=> From (d), C arrived after midnight. Hence C was not the detective.
=> Also, from (d) & (e), B was not the detective.
=> So, from (b), we can say that A was the detective.
=> Now, from (f), C was not the murderer.

Finally, from (a) & (d), A came after B and so, A was the murderer.

Correct Neetu, actualy Anil in his reply, lead to his answar with this thought that detective can not be a murderer.

hmmmmmmmmmm
 
:confused: I am not able to draw the solution here, so attaching the file.Though the picture is not drawn so accurately :D.

nice neetu, If u think outside of this 3x3 square than many solution are availble. any way this is a very good puzzle.

try this one
A man has been waiting for his girlfriend in the park Saturday morning for awhile but the girl didn't arive. He took a look at his watch when started to wait. He left when he saw the minute hand switched places with the hour hand on his watch. How long did he wait (h:mm:ss), knowing that he waited more than 1 hours ?
 
Absolutely right Neetu. Sh Sanjeev Balyan rightly stated that if you think outside of this 3x3 square… Actually this puzzle is generally being used for checking the way of thinking of a person (Broaden or narrow).

One more. .
There are some people consisting of Father, Two sons, Mother, Two daughters, One Policeman and One Thief standing on the bank of a river. Everybody has to cross the river. One raft is available. The rules for crossing the river are:
  • A maximum two persons on the raft at a time.
  • The father cannot be stay with any of the daughter without their mother’s presence.
  • The mother cannot be stay with any of the son without their father’s presence.
  • The thief cannot stay with any of the family member if the policeman is not there.
  • Only the father, mother and policeman know how to operate the raft.
There are confused. You can tell them how they can cross the river?
 
Pol +Thief----------> Thief stays

<-------------Pol. is back
pol + son ----------> son stays
<-----------Plo + thief is back
Father + son------>son stays
<-----------father is back
Mother +Father---------> Father stays
<-------------Mother is back
Mother + Daughter-------> Daughter stays
<---------Mother +Father back
Mother +Daughter---------> Daughter stays
<--------Mother back
Now I am finding it difficult to solve further
