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?
Lets assume number is a then - => (2a+ 54)/2 - a => a + 27 - a => 27
So in short whatever number you choose answer will always be 27.
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.
If x stands for 'add', y stands for 'subtract', z stands for 'divide' and p stands for 'multiply' then what is the value of (27 z 3) p 11 x 5?
There is a number which when you multiply by 3 and subtract 2 from the result, then the resulting number is the reverse of the actual number.
What is the smallest number that stands true on the statement?
