Remember: To calculate sacrifice or gain, use the formula Old Share - New Share. - A positive result means a sacrifice. - A negative result means a gain. The total sacrifice must always equal the total gain.
To determine the gain or sacrifice of each partner due to the change in the profit-sharing ratio, we need to calculate the difference between each partner's old ratio and new ratio.
Old Ratio: Anisha 5/10, Deepa 3/10, Charu 2/10.
New Ratio: Anisha 2/10, Deepa 3/10, Charu 5/10.
We compute the gain or sacrifice for each partner as follows:
Conclusion: Anisha's sacrifice is 3/10, and Charu's gain is 3/10.

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 \(P,O,Q\).
