- Statement (A) is correct:
- Both Pakistan (6.3% to 5.3%) and China (10.3% to 6.8%) experienced a decline in GDP growth rates from 1980-90 to 2015-17. - Statement (B) is correct:
- China achieved double-digit GDP growth (10.3%) in 1980-90, making this statement accurate.
- Statement (C) is correct:
- India’s GDP increased from 5.7% to 7.3%, indicating moderate acceleration in 2015-17.
- Statement (D) is incorrect:
- Pakistan's growth rate (6.3%) was higher than India's (5.7%) in 1980-90, but in 2015-17, India's GDP (7.3%) surpassed Pakistan’s (5.3%), making this statement false. Conclusion: Since Pakistan was not ahead of India for the entire period from 1980 to 2017, the correct answer is option (D).


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 \(P,O,Q\).
