The length and the breadth of a rectangle are made to increase and decrease, respectively, by 8% and 10%. What is the percentage increase or decrease in its area?

A vertical pole and a vertical tower are on the same level of ground in such a way that from the top of the pole, the angle of elevation of the top of the tower is $$60^{\circ}$$ and the angle of depression of the bottom of the tower is $$30^{\circ}$$. If the height of the tower is 76 m. then find the height (in ₹) of the pole.
