Let A = { 1,2,3,4,5}. Let R be a relation on A defined
by xRy if and only if 4x ? 5y. Let m be the number of
elements in R and n be the minimum number of
dements from A X A that are required to be added to R to
make it a symmetric relation. Then m + n is equal to:: Relation (Mathematics) Question | DivineJEE | divineJEE
