Which is the following statement is/are true? I. Odd + Odd = Even II. Odd + Odd + Odd = Odd

Which is the following statement is/are true? I. Odd + Odd = Even II. Odd + Odd + Odd = Odd Correct Answer Both I and II

Let’s understand it with example,

Suppose we have 3 odd numbers - 3,5 and 7

If we add any two of the, we get an even number

3 + 5 = 8

3 + 7 = 10

5 + 7 = 12

And if we add all three of them we get an odd number

3 + 5 + 7 = 15
