Can you find a number such that if we multiply that number by 1 or 2 or 3 or 4 or 5 or 6, then the resultant number contains same all digits (of course in a different place)
Create the number 24 using (all of) 1,3,4 and 6. You may add, subtract, multiply and divide. Parentheses are free. You must use each digit only once. Note that you may not "glue" digits together. Powers are not allowed.
Guess a number 1-10, multiply it by 2, now add with 54 and divide by 2. Lastly, subtract the number you guessed 1-10. What number are you left with, and what is unusual about it?
Given below is a figure. You have to fill in the numbers from 1 up to 16 in such a way that you get 29 when you add the numbers in each row.
