Solution:

I am Stamp.

Solution:

Whenever you come across such a question, keep in mind that you have to always start from the last. Otherwise you will always find yourself jumbled up with the things. We have to find the letter between the letter two to the left of C and letter to the immediate of F. Thus we have to find the letter between A and G. Now the letter that lies in the exact middle will be D. Next, we have to go three times right which will lead us to G. One left is next and we will reach F. At last we have to go right twice. Doing that, we will be standing on H.

Thus H is the required letter.

Solution:

This problem can be solved with algebra as well as logical reasoning. We are going to tell you how it is logically possible.

Be it any quantity that was present in the beginning and any liquid as well. We know that we have taken a spoonful from one glass and put it into another. Then, we have taken a spoonful from the other glass and put it into the first glass. So, at the end of it, the quantity of liquid in either glass remains same as it was in the beginning.

Therefore, we can conclude the fact that any amount of coke that is missing in the glass with coke will be present in the lemonade glass. Also, the same quantity of lemonade will be missing from the lemonade glass and will be present in the coke glass.

Solution:

If you see the picture, you can find out seven squares - five 1x1, one 2x2 and one 3x3. See the dotted lines and the black matchsticks to know how we have moved the matchsticks.

Solution:

The chances that the pair you take out is a white pair is zero.

Just analyze the statement carefully. If there are two colored socks in a drawer, there can be three chances if you take out a pair. It can be either black socks or white socks or a mixed of two. But as per the statement the chances of taking out a black pair of socks is 1/2. Therefore, only two chances exist. We do know that there is a mix of white and black socks in the drawer and thus the second chance has to be a mixture of them both. This is the reason why we can deduce that there are three black socks in the drawer and just one white sock. Thus the probability of taking out two white socks will be zero.

Solution:

10 percent of student study all four subjects.

Solution:

Let us denote the four people with A, B, C and D.
A takes 1 minute to cross, B takes 2, C takes 5 and D takes 10.

A and B cross first spending 2 minutes.
A comes back with torch taking 1 minute.
C and D cross taking 10 minutes.
B comes back with torch taking 2 minutes.
Finally, A and B cross the bridge taking 2 minutes.

2 + 1 + 10 + 2 + 2 = 17 minutes

Thus, this is the way they all managed to cross that bridge that night.

Solution:

That person in the picture is the son of the man holding the picture.

Solution:

The two statements have given it out. If you read carefully, you will easily be able to deduce the answer.

We know that everybody is wearing a different color than their names. Now let us begin with the man who noticed the first i.e. Mr. Grey. He is wearing either Pink or Orange. But in the second statement, we already know that the person who is wearing Pink is somebody else. Thus Mr. Grey must be wearing a Orange shirt.

Mr. Pink cannot wear Pink shirt and Orange shirt has already been taken, thus he must be wearing a Grey shirt.

This leaves only one choice for Mr. Orange and he must be wearing a Pink shirt.

Solution:

Since each one of them gave one answer wrong, this means that each one of them gave two answers right.

Let us assume that Student A gave a wrong answer to the first question. This will mean that Student B also gave a wrong answer for the first. This will conclude that the rest of the two answers given by them are correct. However, the answers are different and thus it is not possible.

Thus both Student A and Student B must be right with the first question and the answer to the first is two.

If you keep applying the same logic, you will come to a conclusion that following are the correct answers:
Q1. Two
Q2. Three
Q3. Two

Solution:

Generation Gap

Solution:

This is absolutely possible. It happened because only three people went for fishing that day: The son, his father and his grandfather.

Solution:

one fish, one cat and one dog.

Explanation:
The question might appear a bit difficult in the starting but if you analyze the statements, you will realize that it is just a tricky one.

All except two were fishes and all except two were cats. With these statements we can assume that two of the animals were not fishes and two were not cats. Now one of those animals that are not fishes can be a cat and one of those two animals that are not cats can be a fish. Just carry out the same analysis for the statement that all except two animals were not dogs and you will come across the result i.e.:
In that competition, there was one fish, one cat and one dog.

Solution:

To do it, the marbles must be arranged as the vertices of an octahedron. If you are unsure, check the image below.

Solution:

Since the answers were different every time, the first one cannot be Sarah as that would make the first one a liar. For similar reason, even the second one can’t be Sarah. Therefore, the third one must be Sarah. If she is Sarah, the middle one must be Sue which leaves the left one to be Sally.

Solution:

Of course, the questions has so many details and so many figures, but you have to consider just a few things. First calculate how much time will it take the friends to meet. Since they are meeting half way, they have to travel 18 miles. At the speed of 6 MPH, they will be able to do it in three hours.

Now see the fact that the parrot will keep on flying for three hours at 20 MPH. Thus the total distance that will be covered will be 60 miles.

Solution:

Numbers of the first cube:
1, 2, 4, 0, 5 and 6.

Numbers on the second cube:
3, 1, 2, 7, 8 and 0.

Now you can pick any date and you will be able to show it using these cubes. Remember that you can always use 6 as 9 by inverting it.

This problem has another solution and we leave it for you to deduce.

Solution:

It is perfectly feasible. The forty elephants had forty foreheads.

Solution:

Pick from the box that is labelled as 'chocolates and toffees’. Since it is an incorrect label, it must have either a chocolate or a toffee.

Suppose if you find a chocolate, then label it as chocolate. Now change the box that was labelled as chocolate earlier and label it as toffees and the box labelled as toffees to 'chocolates and toffees. This is because the one that was labelled as toffees (since it is labelled incorrectly) must have either chocolates or both chocolates and toffees. Since we have already found the box that has chocolates, it must have both chocolates and toffees.

Solution:

Draw a pentagonal star. Now place each of the cone at the intersection points and you will get the desired results.
