#1 - Maths Brain Twister Puzzle

A research team went to a village somewhere between the jungles of Africa. Luckily for them, they reached on the day when quite an interesting custom was to be performed. The custom was performed once in a year as they confirmed and was performed in order to collect the taxes from every male of the region.

The taxes were to be paid in the form of grains. Everyone must pay pounds of grain equaling his respective age. Which means a 20 year old will have to pay 20 pounds of grains and a 30 years old will pay 30 pounds of grain and so on.

The chief who collects the tax have 7 weights and a large 2 pan scale to weigh. But there is another custom that the chief can weigh only with three of the seven weights.

Can you find out the weights of the seven weights? Also what is the maximum age of the man that can be weighed for the payment of taxes ?

The oldest age that can be measured with these weights is 122

#2 - Hard River Crossing Logic Puzzle

You must have heard of so many river crossing riddles however this one is a bit tricky one. We have a dysfunctional family on one side of the river which includes mom and 2 daughters, dad and 2 sons, a maid and a dog. Like usual, there is a boat that can hold only two persons at a time (dog counts as one person as well). Obviously, the kids can’t operate the boat and we need an adult for that task.

Here comes the difficulties. The maid must remain with the dog so she can control it or it will head up for a violent biting. The dad cannot be left with the daughters without mom and nor can the mother be left alone with the sons without dad.

Can you help them cross the river?

Hard River Crossing Logic Puzzle

Suppose that everyone is standing at A corner and they have to reach the B corner

Let the housemaid and Dog go to corner B first and housemaid returns back to corner A.

Next, the housemaid and the first son go to B and she comes back along with the dog.

Now the father and the second son go to B and father comes back.

Mother and Father go to B and the mother comes back.

Housemaid and Dog go to B and the father comes back.

Father and mother goes to B and Mother returns back.

Mother and first daughter go towards B, Housemaid and Daughter returns back.

Housemaid and second Daughter go to B and Housemaid comes back.

Housemaid and Dog goes to B.

So, everyone has reached the other side of the river successfully.

#3 - Hard Logic Problem

There is a town named Springville. In that town you can find extremely hilarious facts. None of the resident has 456,789 hairs. The number of residents are more than the number of hair in any one of the.

Can you find out the largest number of residents in such a scenario?

Hard Logic Problem

The answer is 456,789.

Let us begin with two residents. The number of hairs on their head can be zero and one. If we extrapolate the fact, we will come to know that the number of hairs with 'n' number of residents will always range from zero to (n-1).

If we go above 456,789 to 456,790 with none of the residents having 456,789 hairs, the number of hairs on them will be different and one of them must have more than 456,789 which will clearly violate the fact that the number of residents are more than hairs on an individual.

#4 - Smart Thief Statment Puzzle

A thief was presented in the court of a king. For a judgment, the king asked him to make any statement. If the statement was to be true, he would be burnt alive and if the statement was to be false, he would be thrown in the sea. But after hearing the statement, the king had to let him go.

What did the thief say ?

Smart Thief Statment Puzzle

I will be thrown into the sea. Now if the king threw him in the sea, the statement will come as true and thus he will have to be burnt alive. But if the king burnt him, the statement will come out as false. Thus the king had no choice but to leave him.
