Given:
Capital of Daya = ₹5,00,000
Capital of Deena = ₹6,00,000
Interest on capital = 12% p.a.
Profit-sharing ratio = 3 : 1
Case (i): Profit = ₹2,00,000
Interest on Daya’s capital = $5,00,000 \times 12\% = ₹60,000$
Interest on Deena’s capital = $6,00,000 \times 12\% = ₹72,000$
Total Interest on Capital = ₹60,000 + ₹72,000 = ₹1,32,000
Since profit (₹2,00,000) is greater than total interest (₹1,32,000), full interest can be paid.
Distribution:
- Daya gets ₹60,000
- Deena gets ₹72,000
Balance profit = ₹2,00,000 – ₹1,32,000 = ₹68,000
Divide remaining profit in 3 : 1 → Total parts = 4
- Daya = $₹68,000 \times \dfrac{3}{4} = ₹51,000$
- Deena = $₹68,000 \times \dfrac{1}{4} = ₹17,000$
Final distribution:
- Daya = ₹60,000 + ₹51,000 = ₹1,11,000
- Deena = ₹72,000 + ₹17,000 = ₹89,000
Case (ii): Profit = ₹66,000
Total interest required = ₹1,32,000
Since profit is less than interest payable, it is distributed in ratio of interest on capital:
$60,000 : 72,000 = 5 : 6$
Total parts = 11
Distribution:
- Daya = $₹66,000 \times \dfrac{5}{11} = ₹30,000$
- Deena = $₹66,000 \times \dfrac{6}{11} = ₹36,000$
In this case, no further profit is available beyond interest.
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 \(P,O,Q\).
