Question
State whether the given pair of set is equal or equivalent.
M = {multiples of 2 and 3 between 10 and 20} and
N = {multiples of 2 and 5 between 10 and 20}.
Solution
M = {multiples of 2 and 3 between 10 and 20}
= {12, 14, 15, 16, 18}
and N = {multiples of 2 and 5 between 10 and 20}.
= {12, 14, 15, 16, 18}
These are equal sets as these have same and equal number of elements.
