[ alt="13.08.2018.023" src="//storage.googleapis.com/tb-img/production/18/08/13.08.2018.023.PNG">

Area of the cat door = 25 × 25 cm2 = 625 cm2 = 0.0625 m2

Area of the door including the cat door = 2.5 × 1 + π × (0.5)2 m2 = 3.285 m2

Area of wood required = 3.285 - 0.0625 m2 = 3.2225 m2

Rate of wood = Rs. 500/m2

∴ Total cost of wood = Rs. 500 × 3.2225 = Rs. 1611.25

Man's attitude to various animals changed many times in the course of centuries. From indifference or practicality, he went on to adoration and deification, and thento hatred. Ancient Egyptians, for example, highly appreciated the cat's ability to destroy rodents. The cat was much superior in this respect to the grass­snakes andweasels they had kept in their houses before.

The goddess of the Moon, fertility and child­birth, Bast herself was portrayed by the Egyptians as a woman with a cat's head. Sumptuous temples were built to this goddess, where cats were kept in luxury and fed the choicest of foods. They had their own priests and votaries, more numerous as a matter of fact than any other sacred animal could boast.

Historically, the production of wood charcoal in locations where there is an abundance of wood dates back to a very ancient period, and generally consists of piling billets of wood on their ends so as to form a conical pile, openings being left at the bottom to admit air, with a central shaft to serve as a flue. The whole pile is covered with turf or moistened clay. The firing is begun at the bottom of the flue, and gradually spreads outwards and upwards. The success of the operation depends upon the rate of the combustion. Under average conditions, 100 parts of wood yield about 60 parts by volume, or 25 parts by weight, of charcoal; small-scale production on the spot often yields only about 50%, while large-scale became efficient to about 90% even by the seventeenth century. The modern process of carbonizing wood, either in small pieces or as sawdust in cast iron retorts, is extensively practiced where wood is scarce, and also for the recovery of valuable byproducts (wood spirit, pyroligneous acid, wood tar), which the process permits. The information given, if accurate, most strongly supports which of the following?
