Lencho wrote the letter to God as he thought that he would be the only one to help him in his bad times. He wrote a letter addressing to God to send him 100 pesos so that he and his family can survive in such a difficult situation. The postmaster received the letter written by Lencho.

\sf\red{⟶}Let x∈C

Suppose x∈A⇒x∈A∩C

⇒x∈A∩B(∵A∩C=A∩B)

Thus x∈B

Again suppose x∈/A⇒x∈C∪A

⇒x∈B∪A⇒x∈B

Hence C⊆B .......(1)

Similarly we can show that B⊆C .....(2)

Commbining (1) and (2) we get B=C
