A = {2, 4, 6, 7}, B = {1, 2, 3, 6}, C = {4, 5, 6} হলে, (A ∩ B) ∪ C = কত ?

প্রশ্ন: A = {2, 4, 6, 7}, B = {1, 2, 3, 6}, C = {4, 5, 6} হলে, (A ∩ B) ∪ C = কত ?

সমাধান:
দেওয়া আছে,
A = {2, 4, 6, 7}
B = {1, 2, 3, 6}
C = {4, 5, 6}

তাহলে,
(A ∩ B) = {2, 4, 6, 7} ∩ {1, 2, 3, 6}
= {2, 6}

∴ (A ∩ B) ∪ C = {2, 6} ∪ { 4, 5, 6}
= {2, 4, 5, 6}
