Gross Profit = 20% of Sales → COGS = 80% of Sales = ₹8,00,000
⇒ Total Sales = ₹10,00,000
Cash Sales = ¼ of Credit Sales
Let Credit Sales = x, then Cash Sales = x/4
Total Sales = x + x/4 = 5x/4
⇒ 5x/4 = 10,00,000 ⟹ x = ₹8,00,000
⟹ Credit Sales = ₹8,00,000
Average Trade Receivables = Credit Sales / Trade Receivables Turnover Ratio (TRTR)
= ₹8,00,000 / 5 = ₹1,60,000
Let Opening Trade Receivables = x, then Closing = x + ₹40,000
Average = (x + (x + 40,000)) / 2 = (2x + 40,000) / 2
⇒ (2x + 40,000) / 2 = ₹1,60,000
⇒ 2x + 40,000 = 3,20,000 ⟹ x = ₹1,60,000
Opening Trade Receivables = ₹1,60,000
Closing Trade Receivables = ₹2,00,000
Final Answer: Opening = ₹1,60,000, Closing = ₹2,00,000

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 \(P,O,Q\).
