I am thinking of a five-digit number such that:
The first and last digits are the same, their submission is an even number and multiplication is an odd number and is equal to the fourth number. Subtract five from it and we obtain the second number. Then divide into exact halves and we get the 3rd number.

What number I am thinking of?

How do you go from 98 to 720 using just one letter?

If I remove one from eleven it becomes Ten and if I remove one from nine also becomes Ten. How?

Which tank will fill first?

Which three-digit number, made of consecutive digits, like 567, is 2 less than a cube and 2 more than a square?

What is the next shape from answers A, B, C, and D figure?

I cry without having a voice.
I fly without having wings.
I bite without having teeth.
I whisper without a mouth.

Who am I?

The owner of a popular clothing store comes up with his own method of pricing items. A vest costs $8, socks cost $10, a tie costs $6, and a blouse costs $12. Using the owner’s method, how much would a pair of underwear cost?

Can you move two match sticks to make it 430?

You see me once in June, twice in November, and not at all in May. What am I?
