let A,B and C be three sets.If A belongs to B and B is a subset of C, is it true that A is a subset of C????PLZ EXPLAIN THIS QUESTION AND TRY TO GIVE ONE EXAMPLE ALSO...GIVE REPLY FAST

If A belongs to B,then the set A is an element in set B.if B is a subset of C then all elements of B are present in set C.so set A is an element in set C.therefore Set A belongs to set Cand it is not a subset of set C.theansweris FALSE

No. 

Let A={1}

B={{1},2}  note that 1 here is not element, it is set A as A belongs to B

C={{1},2,3}

So we can say b is subset of C .but A¢C as in setA, 1 is element but in setC 1 is setA not element...
