1.	Is set {x : x is a natural number x7} a null set?(a) True(b) FalseI got this question during an interview.My question is from The Empty Set topic in section Sets of Mathematics – Class 11
Answer» The CORRECT option is (a) True The explanation is: A number less than 5 cannot be greater than 7. If we plot points less than 5 on the number LINE and then plot numbers greater than 7 on it we find, no point is COMMON to both so, it is a null set.
