Hari, Chander, Prakash and Govind were partners in a firm sharing profits and losses in the ratio of 5 : 3 : 1 : 1. On 1st April, 2024, Hari retired and his share was acquired equally by Chander, Prakash and Govind. The new profit sharing ratio of Chander, Prakash and Govind will be:
Step 1: Old ratio = Hari : Chander : Prakash : Govind = 5 : 3 : 1 : 1
Total parts = \( 5 + 3 + 1 + 1 = 10 \)
Step 2: Hari’s share = \( \frac{5}{10} = \frac{1}{2} \)
His share is acquired equally by Chander, Prakash and Govind. So each gets: \[ \frac{1}{2} \div 3 = \frac{1}{6} \]
Step 3: Remaining partners' new shares:
- Chander: \( \frac{3}{10} + \frac{1}{6} = \frac{18 + 5}{60} = \frac{23}{60} \)
- Prakash: \( \frac{1}{10} + \frac{1}{6} = \frac{6 + 10}{60} = \frac{16}{60} \)
- Govind: \( \frac{1}{10} + \frac{1}{6} = \frac{6 + 10}{60} = \frac{16}{60} \) \[ \text{New Ratio} = 23 : 16 : 16 \] Now simplify this to smallest whole number ratio: - Multiply each term by LCM of denominators (60 not needed here), or use original format:
Let’s express everything in terms of a total of 15 (common multiple of 5 and 10):
Old Ratio = 5 : 3 : 1 : 1 → Multiply by 3 → 15 : 9 : 3 : 3
- Hari's share = 15 parts
- Share acquired equally: 15 ÷ 3 = 5 parts each to Chander, Prakash, Govind \[ \text{New Ratio:} \\ \text{Chander: } 9 + 5 = 14 \\ \text{Prakash: } 3 + 5 = 8 \\ \text{Govind: } 3 + 5 = 8 \]
New ratio = 14 : 8 : 8 Simplify by dividing by 7 : 4 : 4

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 \(P,O,Q\).
