NDA Model Paper Set-2

Test Preparation on NDA Model Paper Set-2

Consider the following statements :

I . Any set A is comparable with itself.

II. {0} is a singleton set.

III. {?} is an empty set. Of these statements

1I and III are true
2II and III are true
3I and II are true
4I, II and III are ture.

I. A A, so A is comparable with itself. II. {0} is a set containing one element. So it is a singleton set. III. {?} is a set containing one element, namely ?. So that statements I and II are true and statement III is false.
