A) દેવ - દાનવ B) પાન – પર્ણ C) મોટા – નાનાં
D) ડાહયા - ગાંડા​

Answer 1

Answer:

For each of these relations on the set [1, 2, 3, 4], we can decide whether it is

1. reflexive,

2. symmetric,

3. antisymmetric,

4. transitive.

;- [(2, 2),(2, 3),(2, 4),(3, 2),(3, 3),(3, 4)]

• Not reflexive because we do not have (1, 1), (3, 3), and (4, 4).

• Not symmetric because while we we have (3, 4), we do not have (4, 3).

• Not antisymmetric because we have both (2, 3) and (3, 2).

• Thus , Transitive because if we have (a, b) in this relation, then a will be either 2 or 3. Then (2, c)and (3, c) are in the relation for all c 6= 1.
