By definition, a proposition is a declarative statement that is either true or false, exclusively, therefore: a) "Boston is the capital of Massachusetts" is a declarative statement, and Boston is the capital of Massachusetts, therefore this is a true declarative statement, and therefore a proposition. b) "Miami is the capital of Florida" is a declarative statement, and Miami is not the capital of Florida, therefore this is a false declarative statement, and therefore a proposition. c) "2 + 3 = 5" is a declarative statement, and 2 + 3 = 5 is true, therefore this is a proposition. d) "5 + 7 = 10" is a declarative statement, and 5 + 7 = 10 is false, therefore this is a proposition. e) "x + 2 = 11" is a declarative statement, however, there is no definitive truth value associated with this statement using the given information. For instance, if x = 9, then this statement is true, but if x = 3, then this statement is false. Since there is no way to determine the value of x with the given information, this is not a proposition. f) "Answer this question." is an imperative, not declaratory, statement, and is therefore not a proposition.

Table of contents RD Sharma Class 12th Exercise 1.1 deals with also need to solve exercise problems. This is where Career360 comes to help. It contains expert-created solutions of the chapter 'Relations.' They have plenty of example problems which the students can practice to develop their skills. RD Sharma Class 12 Solutions Chapter 1 Relations - Other Exercise Relations Excercise: 1.1 Answer : Reflexive, symmetric, transitive. Hint : If is reflexive If is symmetric If is transitive Given : Solution : A relation on set A is said to be reflexive if every element of A is related to itself. Thus, is reflexive A relation on set A is said to be symmetric relation if for all i.e. A relation on set A is said to be transitive relation If i.e and for all Now, let's get back to the actual problem For Reflexive : and work at same place Similarly, and work at the same place. So, is reflexive. For Symmetric : It is given that and work at the same place. So, we can say that and work at the same place. So, is symmetric. For Transitive: Let be a person such that and work at the same place. And we know that and work at the same place. So, we can say that and work at the same place. So, is Transitive. Answer : Reflexive, symmetric, transitive. Hint : If is reflexive If is symmetric If is transitive Given : Solution : A relation on set A is said to be reflexive if every element of A is related to itself. Thus, is reflexive A relation on set A is said to be symmetric relation if for all I.e....
