To find the cost of painting a wall we need to find the perimeter of the wall.

(c) Total cost is Rs.330

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....

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

MC = AC When Average Cost is constant, AC curve is at its minimum point. At this point, MC curve cuts AC curve, which implies MC = AC.

The relationship between AC and MC is explained with the help of the following schedule:   Output TC(Rs.) AC(Rs.) MC(Rs.) 0 10 ∞  - 1 20 20 10 2 28 14 8 3 34 11.3 6 4 38 9.5 4 5 42 8.4 4 6 48 8 6 7 56 8 8 8 72 9 16 (i) So long AC is falling, AC is greater than MC. (ii) When AC is rising, AC...

Cost of a dozen pens (12 pens) = Rs.180  Cost of 1 pen = 180/12 = Rs.15  Cost of 8 ball pens = Rs.56  Cost of 1 ball pen = 56/8 = Rs.7  Ratio...

To find the cost of a frame of a picture, we need to find the perimeter of the picture. True

Let the cost of a chair be Rs.x and that of a table be Rs.y, then  5x + 4y = 5600 ……..(i)  4x + 3y = 4340 ……..(ii)  Multiplying (i) by 3 and...

Let the cost of a spoon be Rs.x and that of a fork be Rs.y. Then  23x + 17y = 1770 ……….(i)  17x + 23y = 1830 ………(ii)  Adding (i) and (ii), we...

Let the cost of each pencil be Rs. x and that of each pen be Rs. y.  Then, we have:  5x + 7y = 195 ………(i)  7x + 5y = 153 ………(ii)  Adding (i)...
