    Sir , what if both even and natural number set is finite . natural={1,2,3,4,5} even ={ 0,2,4,6}
    Are they equal now or not ?
    Please reply.

      When its finite, they are not equal, |N| > |E| I guess

    Sir even numbers can be negative too how will we map that

    0 is also even number.How will you map that?

      if 0 is included then we can map i to 2*i-2 instead of i to 2i

      O is also natural number. Check ISO 80000-2 standard definition of natural numbers.

    Sir in the equality of number of elements in natural vs even number.
    Can we solve it by ?
    As both have infinity numbers in there set
    So infinity + something = infinity
