Let A = {p, q , r}. Which of the following is an equivalence relation on A ?
(i) R = {(p, q), (q, r), (p, r) (p, p)}
(ii) R = {(p, p), (q, q), (r, r) (q, p)}
(iii) R = {(p, p), (q, q), (r, r)}
(iv) R = {(p, p), (q, q), (r, r), (p, q), (q, r), (p, r)}
(v) R = {(p, p), (q, q), (r, r), (p, q), (q, p)}

Text Solution
Verified by ExpertsThe correct answer is:
(i) (q, q ); (ii) (p, q); (iv) (q, p)
(iii) & (v)
Sol. (i) (q, q ) 
R (ii) (p, q) 
R (iv) (q, p)
