Riddle: I Had $ 13.00. My mom gave me $ 10.00 while my dad gave me 3 30.00. My aunt and uncle gave me 1 100.00. I had another 5 5.00. How much I have

Answer: the correct answer is 18 dollars. If you read the Question carefully, the question about your first money with ” how much money did you really have?”.

The money you had is dólares 10. That’s before his parents and relatives gave him extra money.

However, since the logic and timing of the verb tense are in the past, it is safe to assume that the question refers to the money you originally had before receiving external money from someone else.

So you originally had dólares 13 and another dólares 5 with you, which adds up to dólares 18.

A dental insurance salesman calls the doorman of a house who asks: How many children do you have and how old are they? Since the price of dental insurance can vary according to age.

The woman, who really wanted to waste the seller’s time, says:

Woman: If you multiply the ages of the 3, you get the number 36.

The seller, stays a while doing calculations, and answers:

Seller: Not enough, I need more information.

Woman: If you add the ages of my 3 children, the result is today.

Seller: I still can’t calculate it

Woman: oh of course, how stupid I am, with this data you will surely be able to calculate it, my eldest son plays the ukulele.

Seller: Now yes!

How is this conversation possible? What calculations was the seller doing? Could you explain it?

” Answer: “

With the first clue, a trio of factors multiplied together, gives us 8 different options:

    • 1x 1x 36 = 38
    • 1x 2 x18 = 21
    • 1x 3 x12 = 16
    • 1x 4 x9 = 14
    • 6x 6x 1 = 13
    • 2x 2x 9 = 13
    • 2x 3 x6 = 11
    • 3 x3x 4 = 10

Faced with so many options, the seller requested new information. The woman told him that it was today, but the salesman, who surely knew what day it was, still told him that it was not enough. That means it was about the 13th.

If it had been day 11, for example, the seller would have already been able to deduce that it was the 2x3x6

As it was the 13th, I needed more information:

With the last track, the eldest playing the ukulele, we know it is the combination, 2x2x9, since in the other, 6x6x1, there is no distinguishable eldest son.

An alumni reunion is held in the schoolyard. In total, 20 people and the former math teacher attend. They all greet each other by shaking hands with each other.

When they finish greeting each other, the teacher says:

Can you tell me how many handshakes have occurred in total?

” Answer: “

210 handshakes.

If we assume that there are only 4 people, the formula would be the following:

4 × 3/2 = 6

We multiply by 3 because each person does not toast with himself, and we divide by 2, because the same greeting from A with B and then B with A. is not counted twice.

If we increase the number of people to 21, the formula would be:

21 × 20/2 = 210

In a community of 10 neighbors, a majority agree to paint the facade.

The manager does the math and asks each neighbor for an amount of money.

The first and third parties do not agree and decide not to pay and declare themselves delinquent.

The administrator, takes up his calculations and tells the rest of the 8 neighbors:

Because we have 2 delinquent neighbors, with the money you have put in it does not come to pay the painter. You will have to pay 10 dollars more per neighbor.

According to these data. Could you calculate how much it costs to paint the facade?

” Answer: “

Painting the facade costs = $ 400.

Initially it was $ 40 each neighbor, but since there are 2 who do not want to pay, we only have $ 320, $ 80 is missing.

Those $ 80 missing is solved by adding $ 10 more per neighbor.

Antonio needed to buy a new computer that cost $ 520. Since he had no money, he decided to sell his old music records. He put an ad on the Internet offering each album for $ 20, or if they preferred, there was the possibility of making an offer of 3 discs for $ 40.

After a week, Antonio had managed to raise the 520 dollars, and for this he needed to sell 32 records.

Can you calculate how many records he sold without an offer, at $ 20 each? And how many offers did you get?

” Answer: “

14 old records.

If I hadn’t made any bids, it would have been 32 records X $ 20 = $ 640.

Which means there is a $ 120 difference you lost in your discounts.

With each offer he lost 20 dollars, then he sold 6 offers, equivalent to 18 records.

It only remains to subtract:

32 – 18 = 14


A coin collector has bought 9 exactly the same pieces, but the seller has told him that one of the coins is a fake and weighs a gram more than the others.

It has a Roman scale with two plates, one on each side.

Is it possible to find out which is the counterfeit coin by using the scale twice?

How would you do it?

” Answer: “

We divide the coins into 3 groups of 3.

We put one group on the first plate, another group on the second plate. If the scale does not move, it means that the false coin is in the third group, on the other hand, if one of the plates goes down, it means that the false coin is in that group.

Now that we know the group of 3 coins, we do the same but with them 3.

1 coin in the first plate, another in the second. If the scale does not move, it is the third coin, on the other hand, if some plate goes down, it means that it is the false coin.
