Enumerate the elements of the following relations from the s

Enumerate the elements of the following relations from the set A of positive integers less than or equal to 10 to the set B of positive integers less than or equal to 30.

An element a of A is related to the element b of B if b = 3 × a

An element a of A is related to the element b of B if b = 2 × a - 1

Solution

Elements of A can be 1,2,3,4,5,6,7,8,9,10 (positive integers less than or equal to 10)

i ) Elements of A if An element a of A is related the element b of B if b= 3 * a

set of A can be written as { 1, 2,3,4,5,6,7,8,9,10}

set of B can be written as { 3 6 9 12 15 18 21 24 27 30}

ii) Elements of A if An element a of A related to the element b of B if b= 2 * a-1;

set of A can be written as { 1, 2,3,4,5,6,7,8,9,10}

  set of B can be written as { 1 3 5 7 9 11 13 15 17 19 }
