The red one says, 'We have 25 legs altogether.'


Can you identify the colour of the servant who is speaking the truth?

Here is a mathematical challenge that will not only engage your brain but also measure your quick-thinking abilities. If you can successfully identify the missing number in such a short span, you are demonstrating exceptional intellectual qualities.

Three friends decide to distribute the soda cans they had among them. When all of them had drunk four cans each, the total number of cans that remained was equal to the cans each one of them had after they had divided the cans.

It can be easily calculated that the digits 0 to 9 can be arranged into 3628800 distinct ten-digit numbers.

But do you know how many of these numbers are prime?

What is 3/7 chicken, 2/3 cat and 2/4 goat?

Can you arrange four 9's and use at most 2 math symbols, to make the total 100?
