{1,5}
{2,4}
{2,3,4}
{}

hint Hint:

Write down all the elements which are outside A and B.

The correct answer is: {1,5}

$A equals open curly brackets 2 comma 4 close curly brackets B equals open curly brackets 3 close curly brackets U equals open curly brackets 1 comma 2 comma 3 comma 4 comma 5 close curly brackets S e t space r e p r e s e n t i n g space n e i t h e r space A space n o r space B equals U minus open parentheses A U B close parentheses equals open curly brackets 1 comma 2 comma 3 comma 4 comma 5 close curly brackets minus open curly brackets 2 comma 3 comma 4 close curly brackets equals open curly brackets 1 comma 5 close curly brackets$

Two metal cubes $A$ and $B$ of same size are arranged as shown in the figure. The extreme ends of the combination are maintained at the indicated temperatures. The arrangement is thermally insulated. The coefficients of thermal conductivity of $A$ and $B$ are $300 W divided by m ℃$ and $200 W divided by m ℃$ , respectively. After steady state is reached, the temperature of the interface will be
