1.	The digit in unit's place of a number is 5. If the number lies between 150 and 200, will itbcomposite or prime?
Answer» For any integer greater than 5, where the units digit is 5 then that number can be expressed as the product of n and 5. As such, the number is composite. Therefore all numbers in the range 150 to 200 that have a units digit of 5 are composite,.
