Vimal, Bose and Ghosh were partners in a firm sharing profits and losses equally. On 1st April, 2024, Bose retired from the firm and the new profit sharing ratio between Vimal and Ghosh was decided as 4 : 3. On Bose’s retirement, the goodwill of the firm was valued at 2,10,000. It was decided to treat goodwill without opening goodwill account. By what amount will the partners’ capital accounts be debited or credited for the treatment of goodwill on Bose’s retirement?
Step 1: Old ratio (Vimal : Bose : Ghosh) = 1 : 1 :\(\Rightarrow\)Each had \( \frac{1}{3} \) share
Step 2: New ratio between Vimal and Ghosh = 4 : 3\(\Rightarrow\)
Vimal = \( \frac{4}{7} \), Ghosh = \( \frac{3}{7} \)
Step 3: Calculate gain for each continuing partner:
- Vimal’s gain = \( \frac{4}{7} - \frac{1}{3} = \frac{12 - 7}{21} = \frac{5}{21} \)
- Ghosh’s gain = \( \frac{3}{7} - \frac{1}{3} = \frac{9 - 7}{21} = \frac{2}{21} \)
Step 4: Bose’s total share = \( \frac{1}{3} = \frac{7}{21} \), which is being distributed between Vimal and Ghosh in the ratio 5 : 2.
Step 5: Total goodwill = 2,10,000\(\Rightarrow\)Bose’s share = \( \frac{1}{3} \times 2,10,000 = 70,000 \)
Step 6: Distribute 70,000 in 5 : 2 ratio:
- Vimal = \( \frac{5}{7} \times 70,000 = 50,000 \)
- Ghosh = \( \frac{2}{7} \times 70,000 = 20,000 \)
Step 7: Entry (without opening goodwill account):
Vimal’s A/c Dr. & 50,000
Ghosh’s A/c Dr. & 20,000
To Bose’s A/c & 70,000

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 \(P,O,Q\).
