Question

Which of the following set is a universal set for the other four sets O Set of even natural numbers O Set of odd natural numbers O Set of natural numbers Set of integers O Set of negative numbers​

Answer 1

We know that N⊂Z where N represents set of natural numbers and Z represents set of all positive and negative integers.

Since N⊂Z,

(a),(b),(c) are subsets of (e) ...(1)

Since Z represents set of all positive and negative integers.

(d) is a subset of (e) ...(2)

From (1) and (2) we get

(a),(b),(c),(d) are subsets of (e).

Hence (e) is the universal set for the other four sets.
