- A subset H of a group(G,*) is a group if
- If A = {1, 2, 3} then relation S = {(1, 1), (2, 2)} is
- Which of the following statements is true?
- Let A = {1, 2, .....3 } Define ~ by x ~ y ⇔ x divides y. Then ~ is

- The set of all real numbers under the usual multiplication operation is not a group since
- If (G, .) is a group such that (ab)- 1 = b-1 a-1, ∀ a, b ∈ G, then G is a/an
