Solution:

Circle Under the Eyes.

Solution:

There can be three cases for this question.
1) X and Y are present in the same row.
In this case, Y will be the tallest in the row => Y is taller than X.

2) X and Y are present in the same column.
In this case, X will be the shortest of the column => Y is taller than X.

3) X and Y are present in different rows and different columns. Suppose that the child standing in X’s column and Y's row is Z. Then:
Y is taller than Z and Z is taller than X => Y is taller than X.

Therefore, in any of the above cases, Y is taller than X.

Solution:

I am stuck in the middle of the hurricane.

Solution:

In the given statement, the letters represent their equivalent position in the alphabets.
A + A = 1 + 1 = 2 = B
B + B = 2 + 2 = 4 = D
A + D = 1 + 4 = 5 = E

Hence,
B + D + E = 2 + 4 + 5 = 11 = K

Solution:

34293

Solution:

1/6227020800

Explanation
This can be solved through a simple mathematical equation.

N cards have n! permutations.
Therefore, the probability of obtaining a specific one by chance is 1/n!

Now, in this particular case, n = 13
Therefore, the required probability is 1/6227020800

Solution:

Solution is shown in image below

Solution:

You are the ship captain. Read the first sentence again. Therefore, the color is same as your eyes color.

Solution:

On the faces of the first dice, you can write 0, 1, 2, 3, 5 and 7
On the faces of the second dice, you can write 0, 1, 2, 4, 6 and 8.

It is simple to crack. Basically, we need 1 and 2 on both the dices to display 11 and 22. Also, we need 0 on both the dices to display dates from 01 to 09.

Now we have taken every number on either dice except. This is the tricky part. Whenever you want to use a 9, you can simply rotate the face with 6 180 degrees.

Solution:

Bear

Explanation:
Bone - one + ear
= B + Ear
=> Bear

Solution:

19(snake) + 1(Echidna) + 80(Bird) Egg =>100 eggs.
Cost:
19*5 + 1 + 4 =>100 pence

Solution:

5 plates.

Explanation
Let's say A is the number of plates washed successfully and B is a number of plates got broken in the cleaning process.
3A – 9B = 240
A + B = 100
=> B=5 (answer) , A(95)
