R = {(x, y) : 3x – y = 0}

(ii) Relation R in the set N of natural numbers defined as
R = {(x, y) : y = x + 5 and x 4}
(iii) Relation R in the set A = {1, 2, 3, 4, 5, 6} as
R = {(x, y) : y is divisible by x}
(iv) Relation R in the set Z of all integers defined as
R = {(x, y) : x – y is an integer}
(v) Relation R in the set A of human beings in a town at a particular time given by
(a) R = {(x, y) : x and y work at the same place}
(b) R = {(x, y) : x and y live in the same locality}

don't let stop this GOLDEN series

[priyal]

Sir plz purani playlist delete mt kijiye ga its a request 🙏

[ankitrajak]

17:13 sir yaha pe transitive hoga ncert mai sahe diya gya hai (a, b) belongs to R hai aur relation mai (b, a) nhi diya gya hai tab bhi ham isse transitive mante hai

[asaif]

17:15 sir isn't the answer right it should be transitive because transitive say if (a, b) belong to R and (b, c) belong to R then it is mandatory for (a, c) to belong to R . BUT here (1, 6) belong to R, but there is no number starting from 6 nor 7 and neither 8 so it is not violating transitive . the answer should be it is transitive .for eg ( a, b) belong to R and there is no (b, c) then it is transitive same with this question
