- $R_1 : {(x_1, x_1), (x_2, x_2)}$
- $R_1 : {(x_1, x_1), (x_2, x_2), (x_3, x_3)}$
- $R_3 : {(x_1, x_1), (x_2, x_2), (x_1, x_3),(x_2, x_4)}$
- $R_3 : {(x_1, x_1), (x_2, x_2),(x_3, x_3),(x_4, x_4)}$

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
(a) Non-reflexive because $\left(x_{3}, x_{3}\right)\notin R_{1}$
(b) Reflexive
(c) Non-Reflexive
(d) Non-reflexive because $x_{4}\notin X$

- Let $ A = \{0, 1, 2, 3, 4, 5\} $. Let $ R $ be a relation on $ A $ defined by $(x, y) \in R$ if and only if $\max\{x, y\} \in \{3, 4\}$. Then among the statements $ (S_1) : $ The number of elements in $ R $ is 18, and $ (S_2) : $ The relation $ R $ is symmetric but neither reflexive nor transitive Options 1. only $ (S_1) $ is true
2. both are true
3. only $ (S_2) $ is true
4. both are false- JEE Main - 2025

- Let \[ L_1 : \frac{x-1}{1} = \frac{y-2}{-1} = \frac{z-1}{-1} \quad {and} \quad L_2 : \frac{x+1}{1} = \frac{y-2}{2} = \frac{z-2}{2} \] be two lines. Let \( L_3 \) be a line passing through the point \( (\alpha, \beta, \gamma) \) and be perpendicular to both \( L_1 \) and \( L_2 \). If \( L_3 \) intersects \( L_1 \) where \( 5x - 11y - 8z = 1 \), then \( 5x - 11y - 8z \) equals:
