Built from Laisha's knowledge because the official page could not be opened or was not found during research (web search quota exhausted); confirm against the body's current notification before relying on it. IASRI (New Delhi) is the main teaching and research centre for agricultural statistics in India and has run the subject since the 1950s. Seat numbers for IARI are 'NR' in the 2026 AIEEA-PG seat table.

Five practice questions, worked

Original questions written to this exam's published syllabus and pattern. Not past papers.

1. A population grows as dN/dt = 0.07N. Its doubling time is about:

  1. 14.3 time units
  2. 9.9 time units
  3. 0.07 time units
  4. 70 time units
Answer and working

B. 9.9 time units

Doubling time = ln 2/r = 0.693/0.07 ≈ 9.9. 14.3 is 1/r, the mean time constant; 70 forgets to divide by the rate in per cent.

2. As a country's per-capita income rises over decades, what usually happens to agriculture's share of GDP?

  1. It falls, while farm output still rises
  2. It rises, because richer consumers spend a larger share of income on food
  3. It stays constant, because food demand grows in step with population
  4. It falls only because agricultural output itself declines in absolute terms
Answer and working

A. It falls, while farm output still rises

Structural transformation: Engel's law (food's share of spending falls as income rises) and faster farm productivity growth shrink agriculture's share while output grows.

3. In a flowchart, a decision with yes and no branches is drawn as a:

  1. Rectangle
  2. Diamond
  3. Parallelogram
  4. Rounded oval
Answer and working

B. Diamond

Rectangles are processes, parallelograms input/output and ovals the start or end.

4. What is binary 1101 in decimal?

  1. 11
  2. 13
  3. 15
  4. 26
Answer and working

B. 13

Place values 8, 4, 2, 1: 8 + 4 + 0 + 1 = 13.

5. By the Bortkiewicz relation, the Paasche price index falls below the Laspeyres price index when which condition holds?

  1. Price relatives and quantity relatives are negatively correlated
  2. Price relatives and quantity relatives are positively correlated
  3. All price relatives are equal across commodities
  4. Base-period expenditure shares are all equal
Answer and working

A. Price relatives and quantity relatives are negatively correlated

P/L - 1 equals the weighted covariance of price and quantity relatives divided by the product of the Laspeyres price and quantity indices; a negative covariance (buyers substitute away from goods whose prices rise most) gives P < L. If all price relatives are equal, P = L exactly.
