was q5(b) wrong. as per icai study mat total capacity is 10000 machine hours. as per question total capacity is 10000 hours.

is machine hours and hours one and the same thing. I don't think so.
I had asked the same question from more than 2 famous teacher of costing but they are giving the Std. reply as if they have just rote the icai study mat and doesn't even bother to read the question came in exam
