Given:
Take any 2, any 3, any 4, any 5 odd numbers
To find:
The sum of the numbers
Calculation:
Let the numbers be 1, 3, 5, 7, 9
Case 1:
Take any two numbers from the above numbers, let the numbers be 1, 3
=> Sum of numbers = 1+3 = 4
Case 2:
Take any three numbers from the above numbers, let the numbers be 1, 3, 5
=> Sum of numbers = 1+3+5 = 9
Case 3:
Take any four numbers from the above numbers, let the numbers be 1, 3, 5, 7
=> Sum of numbers = 1+3+5+7 = 16
Case 2:
Take any five numbers from the above numbers, let the numbers be 1, 3, 5, 7, 9
=> Sum of numbers = 1+3+5+7+9 = 25
If we take an even number of odd numbers, the sum of the numbers will be even and If we take an odd number of odd numbers, the sum of the numbers will be odd
