The whole of India, south of the Himalayas can be climatically treated as a tropical country as the Himalayas provide the barrier effect. 

Indian subcontinent is separated from the rest of Asia by the lofty Himalayan ranges which block the cold air masses moving southwards from Central Asia.

 As a result, during winters, the northern half of India is warmer by 3°C to 8°C than other areas located on same latitudes.

During summer, due to over the head position of the sun, the climate in the southern parts resemble equatorial dry climate.

The seasonal reversal of winds in Arabian Sea and Bay of Bengal give India a typical tropical monsoon climate.

So Indian climate, to be precise, is Tropical monsoon type (a distinct wet and dry climate) rather than just a tropical or half temperate climate.

Mushrooms are heterotrophs. They are not plants or autotrophs.

Every living thing that exists need energy in order to live. This energy ultimately comes from the sun, and only plants, or autotrophs, can directly use this energy to make food. Those organisms that cannot harness the sun's energy are known as heterotrophs.

Mushrooms belong to kingdom Fungi and are heterotrophs because they decompose and consume nutrients from the soil. They are not green so they cannot photosynthesize

For this reason, mushrooms and all other fungi are heterotrophs.

Quantity of fruit juice in the mixture = 70 - [70 x (10/100) ]= 63 litres.

After adding water, juice would form 87.5% of the mixture.

Hence, if quantity of mixture after adding x liters of water, [(87.5) /100 ]*x = 63 => x = 72 

Hence 72 - 70 = 2 litres of water must be added.

Anshu Jamsenpa, the Indian mountaineer from Arunachal Pradesh, has scripted history by becoming the first Indian woman to scale the Mount Everest for the fourth time. She will attempt a double ascent to the world’s highest peak to make it a total five successful climbs. If she is successful with her double ascent this time, Ms Jamsenpa will set a record five climbs of Mt Everest.

          2000xX100 + 4000xY100 = 320

and     2000xX100 + 10000xY100 = 680

x = 4  and  y = 6

x-y = -2

x - 35 = 80x/100 

=> x = 175 

=> 4x/5 = 4x175/5 = 140.

Total ages of 80 boys = 15 x 80 = 1200 yrs.
Total age of 16 boys = 15 x 16 = 240 yrs
Total age of 25 boys = 14 x 25 = 350 yrs.
Average age of remaining boys = 1200 - (240+350) / 80 - (25+15) = 610/41 = 15.25 yrs.
