Explanation of Solution
Given:
Any whole number factor of 20 which is less than 10 is greater than 5
Calculation:
Whole number factors of 20 are 1, 2, 4, 5, 10, and 20
Factors less than 10 are 1, 2, 4, and 5
Hence, the given statement is false as the factors are not greater than 5

Explanation of Solution
Given:
The number of even whole numbers which are less than 10 and are factor of 12 is exactly equal to 3
Calculation:
Factors of 12 are 1, 2, 3, 4, 6 and 12
Even factors less than 10 are 2, 4, and 6
