Question

How many even numbers are between 11 and 99?

Answer 1

Solution:-
To find the even numbers between 11 and 99,
The first odd integer = 11
The last odd integer = 99
Find the difference between them = 99 - 11 = 88
Divide it by the interval (the difference is 2)
= 88/2 
= 44
So, 44 even numbers are there between 11 and 99.
