(i) Sacrificing Ratio:
Old Ratio = 5 : 3 : 2
New Ratio = 4 : 2 : 3 : 1
Total old parts = 10 → Vijay = 5/10, Ravi = 3/10, Raman = 2/10
Total new parts = 10 → Vijay = 4/10, Ravi = 2/10, Raman = 3/10, Kamal = 1/10
Sacrifice = Old Share – New Share:
Vijay = 5/10 – 4/10 = 1/10
Ravi = 3/10 – 2/10 = 1/10
Raman = 2/10 – 3/10 = –1/10 (Gain)
Sacrificing Ratio (Only Vijay and Ravi): 1 : 1
(ii) Journal Entry for Goodwill:
Kamal’s share of goodwill = ₹ 6,00,000 × $ \dfrac{1}{10} $ = ₹ 60,000
This is to be shared between Vijay and Ravi in 1 : 1
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 \(P,O,Q\).
