World's Hardest Riddles With Answers

This is one of the solution how you can do it. There is another way to do it. Run the horses of your mind and find out yourself.

The missing letter in the last box is Z.

Denote each alphabet to the corresponding number. For example, A = 1, B = 2, C = 3 and so on. Now you will find that the center digit is actually the product of the alphabets on both sides. In such case, the missing letter is Z.

=>G(7) * Z(26) = 182

100 will be the next number.

aJust check the spelling of every number. It does not contain the letter T. Thus the next number will be Hundred.

Pirates of Caribbean

It does not matter how much apart are the rungs as no matter at how much speed the water level rises, none of the rungs will go underwater. This is because with the water level rising, even the ship will be rising. Thus none of the rungs go underwater.

Look at the image and see how we did it.

The missing letter is Q.

If you add the three numbers on each square, the value corresponds to the equivalent alphabet in the center. For example 6 + 4 + 4 = 14 and N is the 14th letter. Similarly 14 + 2 + 1 = 17 or the letter Q.

The resulting figure will be C.

It is obvious that it is not feasible to calculate 3^300 as it will take too much of time. So we will use a trick to solve the question. We will calculate the remainder of each power till we find a pattern.

3^1 divided by 5 leaves the remainder 3.
3^2 divided by 5 leaves the remainder 4.
3^3 divided by 5 leaves the remainder 2.
3^4 divided by 5 leaves the remainder 1.
3^5 divided by 5 leaves the remainder 3.
3^6 divided by 5 leaves the remainder 4.

As you can see that the pattern is now repeating itself and it will go on like this till 3^300 and beyond. Since every fourth remainder is same as the first, we will look for the power of 4 only. 300 is divisible by 4. Therefore at the power of 300, the first remainder will repeat itself and the remainder will be 3.

Since at every minute, the cells of yeast are multiplying into two and at 1:22, the dish was half full, it will become full the very next minute i.e. at 1:23.
