Natural growth of population is the outcome of which of the following ?

  • Crude Birth Rate
  • Crude Death Rate
  • Migration
  • Marriages

Select the correct answer from the codes given below :

Answer (d) & explanation

Option (d) is right: natural growth of population is the crude birth rate minus the crude death rate, so it depends on A and B. Option (a), only the birth rate, ignores deaths. Option (b), only migration, is wrong because migration changes the actual population but is not part of natural increase. Option (c), death rate and marriages, is wrong because marriages affect births only indirectly and are not part of the formula. Concept: actual growth equals births minus deaths plus in-migration minus out-migration. The demographic transition model explains how both birth and death rates fall as countries develop. India's rates are measured by the Sample Registration System of the Registrar General, and its population growth has slowed sharply.

Trap

Migration changes the actual population, but natural growth is only birth rate minus death rate.

Which one of the following correctly represents the three key sub-indices of the Financial Inclusion Index (FI-Index) of the Reserve Bank of India (RBI) ?

Answer (c) & explanation

The sub-indices are Access, Usage and Quality (c). The RBI launched the FI-Index in August 2021. It covers banking, investments, insurance, postal services and pension, and gives one value between 0 and 100. Its three parameters are Access (35%), Usage (45%) and Quality (20%). Options (a), (b) and (d) list areas or ideas that are not its sub-indices; GDP contribution and affordability are not parameters.

Notice the logic: usage has the most weight, because an account that is never used does not mean real inclusion. Quality includes financial literacy and consumer protection. The index is published every July, and it has risen steadily, helped by Jan Dhan (2014) and UPI.

Which one of the following best describes the key objective of India's 'Open Network for Digital Commerce' (ONDC) initiative ?

Answer (c) & explanation

ONDC aims to break the dominance of large platforms (c). The Open Network for Digital Commerce, a DPIIT initiative (2021-22), is an open set of rules, like UPI for shopping. A buyer on one app can buy from a seller listed on another app. This interoperability lets small sellers reach buyers without joining a giant platform. Option (a) is wrong: it does not give the government control of transactions. Option (b) is wrong: private players can join; they are not replaced. Option (d) is wrong: it does not force UPI payments.

Notice ONDC's design: it is a not-for-profit company and part of India's Digital Public Infrastructure, along with Aadhaar, UPI and DigiLocker. It now covers food, groceries and mobility too.

Trap

options (a), (b) and (d) use strong words: "all", "replace", "mandate". A public digital platform usually opens a market; it does not take it over.

Which one of the following statements about Unified Payments Interface (UPI) and Central Bank Digital Currency (Digital Rupee) is not correct ?

Answer (d) & explanation

Statement (d) is not correct (d). Under UPI, money moves between bank accounts; the deposit is a liability of the bank. The Digital Rupee (e₹) is like a currency note in digital form, a direct liability of the RBI, not of users or banks. Option (a) is correct: UPI is a payment system, while the e-rupee is sovereign currency. Option (b) is correct: an e-rupee transfer moves value from wallet to wallet with no separate settlement. Option (c) is correct: e-rupee wallet transactions do not appear in bank statements.

Notice the legal base: the RBI Act was amended in 2022 to let the RBI issue a CBDC. Pilots began that year in wholesale (e₹-W) and retail (e₹-R) forms.

Trap

a "not correct" question. Look for the statement that puts the RBI's liability on someone else.

Which of the following statements about Real-World Assets (RWA) Tokenization are correct ?

  • 1. Tokenization is the process of turning real world assets into digital tokens using blockchain technology.
  • 2. Tokenization of real world assets offers 24x7 access, promoting financial inclusion.
  • 3. Tokenization of real world assets will allow the access to high growth investment opportunities for individuals in India.

Select the answer using the code given below :

Answer (a) & explanation

All three statements are correct (a). Statement 1 is right: tokenization turns a real asset, like a building, bond or gold, into digital tokens recorded on a blockchain. Statement 2 is right: tokens can be traded 24x7, which widens financial inclusion. Statement 3 is right: small, fractional tokens let ordinary individuals get into high-growth investments that once needed crores. So options (b), (c) and (d) fail.

Notice the risks: unclear regulation, cyber threats and weak investor protection. In India, related steps include Fractional Ownership Platforms and REITs and InvITs, which already let small investors own slices of real estate and infrastructure. The RBI is also testing tokenized deposits and government securities in sandbox pilots.
