To calculate GDP at Factor Cost, we use the value-added approach. This involves summing the value added by each firm, where value added is the value of output minus the value of intermediate inputs. Then, we adjust for Net Indirect Taxes to obtain GDPFC.
Step 1: Calculate Value of Output for Each Firm
Step 2: Calculate Intermediate Inputs for Each Firm
Step 3: Calculate Value Added by Each Firm
Value Added = Value of Output − Value of Intermediate Inputs
Step 4: Calculate GDP at Market Price (GDPMP)
GDPMP = Sum of Value Added by all firms
= ₹2,100 (Firm A) + ₹2,600 (Firm B) + ₹1,000 (Firm C) = ₹5,700
Step 5: Calculate GDP at Factor Cost (GDPFC)
GDPFC = GDPMP − Net Indirect Taxes
= ₹5,700 − ₹240 = ₹5,460
The Gross Domestic Product at Factor Cost (GDPFC) is ₹5,460.

A racing track is built around an elliptical ground whose equation is given by \[ 9x^2 + 16y^2 = 144 \] The width of the track is \(3\) m as shown. Based on the given information answer the following: 
(i) Express \(y\) as a function of \(x\) from the given equation of ellipse.
(ii) Integrate the function obtained in (i) with respect to \(x\).
(iii)(a) Find the area of the region enclosed within the elliptical ground excluding the track using integration.
OR
(iii)(b) Write the coordinates of the points \(P\) and \(Q\) where the outer edge of the track cuts \(x\)-axis and \(y\)-axis in first quadrant and find the area of triangle formed by points \(P,O,Q\).
