Question

3. MU N = {1,2,3,4,5,6} M={1,2,4} then
which of the following represents
sets is N?​

Answer 1

Answer:

Given M∪N=(1,2,3,4,5,6)

M=(1,2,4)

N=[3,5,6] or [1,3,5,6] or [2,3,5,6] or [4,3,5,6] or

[1,2,3,5,6] or [1,4,3,5,6] or [2,4,3,5,6] or [1,2,4,3,5,6]

These all can be the set 'N' as these when taken union with given 'M' yields M∪N={1,2,3,4,5,6}
