Friend you hardly understood my comment.I never mentioned per capita income as GDP,Per capita income means average income.In average we can divide the total money with population,then we can arrive at per capita income.here total money means the aggregate GDP or GNP.but in our India we take GDP in general(because it reflects exact Indian economic scenario),so GDP/Population gives us per capita income.I hope now your doubt cleared,all the best

21. Hmm. Thanks sir

22. Thanx to team

23. Q 4
C=4/40 =1/10

57. Ganges delta means the fertile planes where River Ganges flows and deposit its alluvial sediments.But Sunderban delta means the collective delta area formed by Ganges,Brahmaputra,Meghana rivers,this is so swampy area(because Meghana river get disappeared here),So we can't attribute this delta's legacy to one river.Hence it is called "Sunderban" delta.

58. Pass is the geographical term which symbolizes the "natural path/way" formed in the process of Orogeny(mountain building process),these passes are exactly formed due to tectonic(under ground geographical plates) slide in addition to Orogeny,we have Hindukush,Himalayas,Karakoram etc. ranges.And Our sub continent is colliding with Eurasian plate.So under extreme thrust our Himalayas undergoing fast sedimentation. and so we got Nathula, shipkila,zheepla passes in the eastern side and Banihal,rohtang lal passes in pirpanjal ranges in the North west India.
