When price is Rs. 20, Quantity demand is 10 units and price is decreas...
Given Information:
Price (P) = Rs. 20
Quantity demand (Q) = 10 units
Price decreased by 5%
Quantity demand increased by 10%

To find:
Marginal Revenue (MR)

Solution:
First, we need to find the new price and quantity demand after the given changes.

New Price = 20 - (5% of 20) = Rs. 19
New Quantity Demand = 10 + (10% of 10) = 11 units

Now, we can calculate the Marginal Revenue using the formula:

MR = (Change in Total Revenue) / (Change in Quantity)

To use this formula, we need to calculate the Total Revenue for both the initial and new situations.

Initial Situation:
Price (P) = Rs. 20
Quantity demand (Q) = 10 units
Total Revenue (TR) = P x Q = 20 x 10 = Rs. 200

New Situation:
Price (P) = Rs. 19
Quantity demand (Q) = 11 units
Total Revenue (TR) = P x Q = 19 x 11 = Rs. 209

Now, we can calculate the Change in Total Revenue and Change in Quantity as follows:

Change in Total Revenue = New TR - Initial TR = 209 - 200 = Rs. 9
Change in Quantity = New Q - Initial Q = 11 - 10 = 1 unit

Finally, we can calculate the Marginal Revenue using the formula:

MR = Change in Total Revenue / Change in Quantity = 9 / 1 = Rs. 9

Therefore, the Marginal Revenue is Rs. 9.

Answer: (c) Rs. 9

When price is Rs. 20, Quantity demand is 10 units and price is decreas...
P=20 , P1=19.     20�5%=1 =20-1 =19 ( decrease)
Q=10 , Q1=11.    10�10% =1 = 10+1 =11(increase)

MR =  P�Q /Q
          =  P1�Q1 - P�Q / Q1-Q
          = 19�11 - 20�10/11-10
           = ₹9
