Tropical rainforests are such rainforests that occur in the region of tropical rainforest climate where there is no dry season and it remain hot and wet.Tropical evergreen rainforest biome provides optimum environmental conditions for the growth of plants and animals because it experience heavy rainfall and high temperature, and extend between 10° N and 10° S latitudes. The biome Tropical rain forests are of mega thermal type because the organisms are adapted to high temperature and wet and humid condition. The maximum development of this biome has taken place in South America, lowland regions in Africa, and the islands off of Southeast Asia, Central America and parts of Australia.

On December 21, the earth is in an equivalent position on the opposite points in its orbit, So the South pole is tipped towards the sun and North pole away from it resulting in 24 hours of darkness at the North pole, as the sun is overhead on the Tropic of Capricorn. This phenomenon is winter solstice; while on June 21, North pole is tipped towards the Sun but the South pole is tipped away from the sun resulting in 24 hours of darkness on the South Pole, as the sun is overhead on the Tropic of Cancer.This phenomenon is summer solstice; while Aphelion is the position of the earth in its orbit when it is at its distant point from the sun.

At   present   US   has   the   largest railway   network   in   the   world. Second is China and third is India.

So A : B : C = 1 5 × 1 7 : 1 6 × 17 : 16 × 18 = 255 : 272 : 288

From statement I, Area of square = 576 sq cm
Side of square = 24 cm
Area of rectangle = l × b
l × b = 600 sq cm
From statement II, Suppose the breadth of the
rectangle is x. Then side of the square = 2x
Combining both the information, we have
x =12 cm
Now, l × 12 = 600

l=60012=50 cm

Required ratio = 5024=2512=25:12

Both the statements together are sufficient.
