hii there,:)
to find out the number:
Ask whether the number is even or odd.
eliminates half of the options.
2nd, ask if it's between 1 to 50 or not.
eliminates other half.
3rd, ask if its a perfect square.
the perfect squares have almost a gap of 10 numbers between, but we would have already ruled out even or odd, so easier to choose the number.
ask if between 9-16, or 25-36 and so on.'
you can also ask if the number is divisible by 2 and 3 or by only 2 or only 3 if it's not a prime number.
this is one strategy.or you can think of a better one! :)
