Today I have a very interesting puzzle for you. Some of you might have heard about this before. Do you know the answer? Here is the puzzle once again.

Three friends went to a restaurant for lunch. When the bill arrived, it came exactly $30. So each person put in $10 towards the bill. The waiter took the money but the manager pointed out that the customers had been overcharged by $5. The dishonest waiter took five $1 coins from the till and kept 2 for himself and gave back the other 3 back to the customers.

Each of the friends had paid $10 minus the $1 they got back for the meal. That is each paid $9 which in total is $27 for all the 3 friends. The waiter had kept $2 making a total of $27 + $2 = $29.

So what happened to the other $1?

Answer

There is no missing dollar here. The friends spent $ 27 together. From that $25 they paid for the bill and the remaining $2 had taken by the waiter. But I have one question for you -Who told you to add $2 to $27?

Today we can have a number problem.O.K?

On his way to school, Jim is knocked down by a car.

He noticed the number of the car.

• The digit in thousand’s place is 4 times the digit in unit place
• The digit in ten’s place is half of the digit in thousand’s place
• The digit in hundred’s place is 3 less than the digit in ten’s place
• Two is in the unit place

Find the number.

I think it is very easy to find out.

Ans: 8142

See the picture below

Can you tell me the answer?

It’s an optical illusion.The hypotenuse of both triangles seem to be straight lines but they’re not.
I think the answer lies in the fact that neither shape is actually a triangle, they are quadrilaterals. They have four sides.

The side that looks like it is the hypotenuse is actually two sides, the corner being where the green and red triangle.
I have searched the web and find an answer here.

If you have any good explanation about this please let me know.

There are 10 trees spaced out equally along my street with one at each end. If I run at a steady speed from one end of the street, I can reach the 5 th tree in just 5 seconds.

How long would it take me to run down the whole street at the same pase?
( No, it is not 10 seconds)

Did you get the answer?

When I reach the 5 th tree I cover 4 trees.
So,time taken to cover 4 trees is 5 seconds.
So, time taken to cover 1 tree is 5/4 seconds.
When I reach the 10 th tree I cover 9 trees.
So, time taken to cover 9 trees( and this is same as the time taken to run down the whole street) is 9 multiplies 5/4
ie 45/4
or
11.25 seconds

Don’t be get angry. I am going to show this.

What is wrong? My calculations or your eating habbits!?

Here is an ancient problem from Bhaskaracharya’s (Indian Mathematician ) Lilavati:

A beautiful maiden, with beaming eyes, asks me which is the number that, multiplied by 3, then increased by three-fourths of the product, divided by 7, diminished by one-third of the quotient, multiplied by itself, diminished by 52, the square found, addition of 8,division by 10 gives the number 2?

Well, it sounds complicated, doesn’t it? No, not if you know how to go about ?



Answer:
28

The method of working out this problem is to reverse the whole process.
