How many odd numbers are there between 32 and 53?
As we know, that number is odd if and only it is not divisible by 2 or in other words every other number is odd number if we take numbers one after another. As 32 is divisible by 2 next number is not divisible by 2 i.e. 33.
Thus list of all odd numbers between 32 and 53 are 33, 35, 37, 39, 41, 43, 45, 47, 49, 51.
So, there are 10 odd numbers in between 32 and 53.
