   Which soil is formed by intense leaching in areas of high temperature and heavy rainfall, is rich in oxides of iron and aluminium, and is found on the Western Ghats?

   • AAlluvial soil
   • BBlack soil
   • CRed soil
   • DLaterite soil
   Show answer & solution

   Correct answer: (D) Laterite soil

   Heavy rain washes away (leaches) silica and lime from the soil, leaving behind oxides of iron and aluminium; this produces laterite soil. It is found on the Western and Eastern Ghats and in parts of the North-East, and suits tea, coffee and cashew. Red soil also contains iron but develops on crystalline rocks in lower-rainfall areas, not by intense leaching. Answer: Laterite soil.

   • CNet Domestic Product (NDP)
   • DPersonal Income
   Show answer & solution

   Correct answer: (C) Net Domestic Product (NDP)

   'Gross' includes depreciation and 'Net' excludes it; 'Domestic' means production within the country's borders. So GDP – depreciation = NDP. GNP = GDP + net factor income from abroad, and NNP = GNP – depreciation. Answer: Net Domestic Product (NDP).

4. Q4hard

   A country's nominal GDP for a year is ₹200 lakh crore and the GDP deflator for that year is 125 (base year = 100). What is its real GDP?

   • A₹250 lakh crore
   • B₹175 lakh crore
   • C₹160 lakh crore
   • D₹225 lakh crore
   Show answer & solution

   Correct answer: (C) ₹160 lakh crore

   Real GDP = Nominal GDP × 100 ÷ GDP deflator. = 200 × 100 ÷ 125 = 20,000 ÷ 125 = 160. (Multiplying by 1.25 instead of dividing gives the wrong figure ₹250 lakh crore.) Answer: ₹160 lakh crore.
