There are two Statements, Assertion and Reason (R).
Assertion : Larger the lead time, larger is the quantity of material required to be stored and larger shall be the amount of working capital required.
Reason (R): If the raw material does not have a record of uninterrupted availability, higher stock levels may be required. Choose the correct alternative from the alternatives given below:
To determine the correct relationship between the Assertion and the Reason (R) given in the question, we must analyze both statements:
Considering the analysis above, the correct answer is:
Both Assertion and Reason (R) are true and Reason (R) is the correct explanation of Assertion.
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 \(P,O,Q\).
