    Call me picky, but I suggested you posted your last topic in 'Homework Help'
    This certainly seems like it would fall in that category as well.
    ...As does all of your other topics.

    I will not do your homework for you. Please reply with the work you have done so far on this problem.

    I have calculated equivalent resistance which comes out to be 480. Thus current comes out 0.1A. Then power comes 4.8W. But wattmeter shows 9.408 reading?

    Perfect. Do take a look at the Ammeters in the drawings to see which part of the circuit is behaving properly.

    Should I find out the loop currents by applying KVL,KCL or is there any other judgement method?

    Yes. Ignore the readings on the ammeters and wattmeter until you have completed some of your calculations.
    If the printed values match your calculations then you can state the components function correctly. Otherwise you know where the faulty component is.
