GIVEN :

If A is a subset of B ,B is a subset of C and C is a subset of A then prove that A =B = C.

SOLUTION :

➢ Given that, A is subset of B

➡ A ⊆ B .......... (1)

➢ And, B is subset of C

➡ B ⊆ C .......... (2)

➢ And also, C is subset of A

➡ C ⊆ A .......... (3)

Now from the equations (1) & (2)

We get, A ⊆ C .......... (4)

Now, the equations (3) & (4) are equal.

So, A = C

Hence, it is proved.
