Question

 M U N = { 7,8,9,10,11,12,} and M = {7,8,10} then which of the following represent set N.​

Answer 1

Answer :-

Given:-

M ∪ N = {7,8,9,10,11,12}

and M = {7,8,10}

So, N = {9,11,12} or {7,9,11,12} or {8,9,11,12} or {10,9,11,12} or {7,8,9,11,12} or {7,10,9,11,12} or {8,10,9,11,12} or {7,8,10,9,11,12}

These all can be the set 'N' as these when taken union with given 'M' yields M U N = {7,8,9,10,11,12}
