85123 If \(x\) and \(y\) are the sides of two squares such that \(y=x-x^{2}\), then what is the rate of change of the area of second square with respect to the area of first square?

85124 A balloon is coming down at the rate of 4 \(\mathrm{m} / \mathrm{min}\) and its angle of elevation is \(45^{\circ}\) from a point on the ground which has been reduced to \(3^{\circ}\), after \(10 \mathrm{~min}\). Balloon will be on the ground at a distance of how many metres from the observer?

85125 The radius of a cylinder is increasing at the rate of \(2 \mathrm{~m} / \mathrm{s}\) and its height is decreasing at the rate of \(3 \mathrm{~m} / \mathrm{s}\). When the radius is \(3 \mathrm{~m}\) and height is \(5 \mathrm{~m}\), then the volume of the cylinder would change at the rate of
