2. Q2medium

   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.

3. Q3medium

   In national income accounting, Gross Domestic Product minus depreciation is called:

   • AGross National Product (GNP)
   • BNet National Product (NNP)
   • 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.
