Given:
Capital of Prathma = ₹ 10,00,000
Capital of Madhyama = ₹ 8,00,000
Capital of Tritiya = ₹ 6,00,000
Rate of Interest on Capital = 10% per annum
Profit-sharing ratio = 2 : 2 : 1
(i) When Net Profit = ₹ 3,00,000
Step 1: Calculate Interest on Capital:
Prathma: $₹\ 10,00,000 \times 10\% = ₹\ 1,00,000$
Madhyama: $₹\ 8,00,000 \times 10\% = ₹\ 80,000$
Tritiya: $₹\ 6,00,000 \times 10\% = ₹\ 60,000$
$\Rightarrow$ Total Interest = ₹ 2,40,000
Step 2: Compare Interest with Profit
Since Profit (₹ 3,00,000) > Interest on Capital (₹ 2,40,000),
$\Rightarrow$ Full interest on capital will be allowed.
Step 3: Remaining profit = ₹ 3,00,000 – ₹ 2,40,000 = ₹ 60,000
This remaining profit is distributed in ratio 2:2:1:
Total ratio = 5 parts
Prathma: $\dfrac{2}{5} \times ₹\ 60,000 = ₹\ 24,000$
Madhyama: $\dfrac{2}{5} \times ₹\ 60,000 = ₹\ 24,000$
Tritiya: $\dfrac{1}{5} \times ₹\ 60,000 = ₹\ 12,000$
Final Distribution:
Prathma: ₹ 1,00,000 + ₹ 24,000 = ₹ 1,24,000
Madhyama: ₹ 80,000 + ₹ 24,000 = ₹ 1,04,000
Tritiya: ₹ 60,000 + ₹ 12,000 = ₹ 72,000
(ii) When Net Profit = ₹ 1,20,000
Step 1: Interest on Capital requirement = ₹ 2,40,000 (as above)
But profit is only ₹ 1,20,000, which is less than interest required.
$\Rightarrow$ Interest will be allowed in the ratio of capital contributions.
Capital Ratio:
10,00,000 : 8,00,000 : 6,00,000 = 10 : 8 : 6
$\Rightarrow$ Simplified = 5 : 4 : 3
Total parts = 12
Proportionate Interest Distribution:
Prathma: $\dfrac{5}{12} \times ₹\ 1,20,000 = ₹\ 50,000$
Madhyama: $\dfrac{4}{12} \times ₹\ 1,20,000 = ₹\ 40,000$
Tritiya: $\dfrac{3}{12} \times ₹\ 1,20,000 = ₹\ 30,000$
Final Distribution:
Prathma: ₹ 50,000
Madhyama: ₹ 40,000
Tritiya: ₹ 30,000

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 \(P,O,Q\).
