You are the captain of a ship. While your ship is sailing, you are struck by a storm and it becomes difficult for you to handle your ship. After an hour of struggle, 15 passengers are swept away by the waves. 15 minutes further into the storm, 10 more people are swept away by the waves. You send the lifeboats down and 4 of them are able to climb the rescue boats. The next wave hits the ship hard and 12 passengers fall off the ship.
Now, can you tell the color of eyes of the ship captain?
You are given with two ropes with variable width. However if we start burning both the ropes, they will burn at exactly same time i.e. an hour. The ropes are non-homogeneous in nature. You are asked to measure 45 minutes by using these two ropes.
How can you do it?
Please note that you can’t break the rope in half as it is being clearly stated that the ropes are non-homogeneous in nature.
All you have to do is burn the first rope from both the ends and the second rope from one end only simultaneously. The first rope will burn in 30 minutes (half of an hour since we burned from both sides) while the other rope would have burnt half. At this moment, light the second rope from the other end as well. Where, the second rope would have taken half an hour more to burn completely, it will take just 15 minutes as we have lit it from the other end too.
Thus you have successfully calculated 30+15 = 45 minutes with the help of the two given ropes.
This is a famous probability puzzle in which you have to choose the correct answer at random from the four options below.
Can you tell us whats the probability of choosing correct answer in this random manner.
You can place weights on both side of weighing balance and you need to measure all weights between 1 and 1000. For example if you have weights 1 and 3,now you can measure 1,3 and 4 like earlier case, and also you can measure 2,by placing 3 on one side and 1 on the side which contain the substance to be weighed. So question again is how many minimum weights and of what denominations you need to measure all weights from 1kg to 1000kg.
A girl liked to collect money in a piggy bank. She bought pink colored piggy bank when she was 10 years old. She put $250 in the box on each of her birthday. Her younger sister took $50 out of her piggy bank on her birthday. The girl died when she was 50 years old due to an incurable disease.
When the piggy bank was opened, it had just $500. How can that be possible?
The girl was born on 29 February. Thus her birthday came once in four years only while her sister was born on a normal day and celebrated her birthday every year. Thus the girl had a chance of depositing money only 10 times in 4 years through which she collected $2500 while her sister took $50 from the piggy bank every year making the total amount to be $2000. Thus when the piggy bank was opened, it had just $500.

Stephen died of heart attack. His soul was received in heaven. He was astonished to find himself as young as he had been in his young adult age. He looked around and there were thousands of young and naked people. His eyes searched to find someone familiar and suddenly he noticed Adam and Eve.
In a friend's get together party on New Year's Eve, a power cut takes place unexpectedly. When the lights go live again, it is found that Joseph, one of the friends has been stabbed to death. Since no one else had the access to the party, the killer is one of the friends only.
Police are called and they search the surroundings for any evidence, but can't find any. Upon checking the pockets of Joseph's pants, they find a pocket calendar and they find out that it has been marked and can also find some numbers written on it.
You can see the calendar attached with this question.
You don't know the name of the friends who were there at the party. Can you still decipher the name of the killer through the picture?
The numbers that have been written over the calendar are:
12, 4, 8 and 3
A few numbers have been circled under particular months. The curious thing is that the numbers that have been written are the same number of corresponding months under which the dates have been marked.
What we can judge by the overall calendar is that the dates that have been marked may refer to the letters at that position in the month's name. In addition, the written numbers can be the position of those letters. Let's simplify below:
12th month is December
The number marked under December = 5
The fifth letter of December = M
4th month is April
The number marked under April = 4
The fourth letter of April = I
8th month is August
The number marked under August is 6
The sixth letter of August = T
3rd month is March
The numbers marked under March are 4 and 5
The fourth and fifth letter of March = C and H
When you combine the letters, you get the name as MITCH.
Therefore, Mitch is the killer.
I bought three toys for my triplet boys (one for each). I placed the toys in the dark store. One by one each boy went to the store and pick the toy. What is the probability that no boy will choose his own toy?
