Cash Flow from Investing Activities:
Proceeds from Sale of Machinery = |42, 000
Purchase of Machinery = |3, 25, 000
Net Cash Flow from Investing Activities = |(3, 25, 000 − 42, 000)
= |(2, 83, 000) (Outflow)
Cash Flow from Financing Activities:
Proceeds from Share Capital = |2, 00, 000
Repayment of Bank Loan = |2, 20, 000
Net Cash Flow from Financing Activities = |(2, 00, 000 − 2, 20, 000)
= |(20, 000) (Outflow)
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 \(P,O,Q\).
