25% of the total cost of a plot of area 280 sq feet is Rs 1,32,370. What is the rate per sq.ft. of the plot?

(a) tube feet 

(e) Let the breadth of rectangular plot = x metre therefor Length = 2x metre According to the question,  2x × x = 2592 or, x2 =2592/2 = 1296 therefor x = √1296 = 36 therefor Lenght of...

(c) Surface area of the cube  = (6 ×82 ) sq. ft. = 384 sq.ft.  Quantity of paint required  =(384/16) kg =24 kg Cost of painting = Rs.(36.50 × 24) = Rs. 876

L            TC        TFC = TC - TVC  TVC = TC - TFC  AFC = TFC/Q AVC = TVC/Q SAC = AFC + AVC  SMC = TCn - TCn -...

(a) Cost of table salt per mole:  Molecular mass of table salt (NaCl) = 23+35.5=58.5  Now, 1000 g of NaCl cost = Rs. 2  Therefore 58.5 g of NaCl will cost = 2/1000...

(c) Total cost is Rs.330

'The equilibrium level of output wiil be 4 units. This is because at this point the two conditions of equilibrium (using MR-MC approach are met . This can be seen...

AVC = ATC We know that, TC=TFC+TVC Dividing both the sides by 'Q', we get Hence, TC/Q = TFC/Q + TVC/Q [.'.TFC = 0] ATC = AVC Graphically, both the cost curves will intersect each other....

The difference between Total Cost and Total Variable Cost is Total Fixed Cost, which remains the same whether the output produced is 1 unit or 100 units.

When Marginal Cost is rising and Average Variable Cost is falling, Marginal cost lies below the Average Variable Cost. MC is less than AVC.
