To solve this problem, we need to determine the share of profits Dinesh receives in the firm after being admitted as a partner.
Aman, Boman, and Chetan originally shared profits in the ratio of 5:3:2. This means:
It is given that Aman surrendered \(\frac{1}{5}\)th of his share to Dinesh. Aman's share before surrendering is \(\frac{1}{2}\).
To find out what fraction of this \(\frac{1}{2}\) Aman gives to Dinesh, we calculate \(\frac{1}{5}\)th of \(\frac{1}{2}\):
\[ \frac{1}{5} \times \frac{1}{2} = \frac{1}{10} \]
Therefore, Dinesh is admitted with a \(\frac{1}{10}\) share in the profits of the firm. The correct answer is \(\frac{1}{10}\).
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 \(P,O,Q\).
