Which statement is the law of diminishing returns?
A. With other inputs held fixed, the extra output from each added unit of a variable input eventually falls
The law of diminishing returns (law of variable proportions) concerns one variable input added to fixed inputs: its marginal product eventually declines. Doubling every input together is a returns-to-scale question, falling average cost with herd size is economies of scale, and total output does not fall from the first unit; it falls only in Stage III.
A cow gives 10.5 litres of milk a day on 2 kg of concentrate and 12.0 litres on 3 kg, other feed unchanged. What is the marginal physical product of the third kilogram?
A. 1.5 litres
MPP = change in output / change in input = (12.0 − 10.5) / 1 = 1.5 L. 4.0 L is the APP at 3 kg (12.0/3), 12.0 L is the total product, and 2.0 L would be the MPP of the second kilogram if the yield at 1 kg were 8.5 L.
In most milk, broiler and egg enterprises, the largest single item of the cost of production is:
B. Feed and fodder
Feed is the largest single cost in almost all intensive and semi-intensive livestock enterprises, frequently half or more of the total, though the exact share varies by system and feed prices. Labour is next on many farms; veterinary costs and depreciation are smaller.
A dairy farmer receives 38 currency units per litre and the consumer pays 56 per litre for the same milk. What is the producer's share in the consumer's rupee?
D. 67.9 per cent
Producer's share = producer price / consumer price × 100 = 38/56 × 100 = 67.9%. 32.1% is the price spread (18 currency units) as a share of the consumer price; 147.4% inverts the ratio; 47.4% expresses the spread as a share of the farmer's price.
In many weekly livestock markets of South Asia, animals are sold by eye estimation rather than on a weighbridge. The main consequence is that:
A. Producers who cannot judge weight as well as traders tend to receive lower prices
Sale by eye estimation favours experienced traders who judge weight and dressing out better than occasional sellers, so farmers are disadvantaged. Weighing and grading are among the reforms that regulated markets aim to introduce.
The three tiers of the Anand pattern of dairy cooperatives are:
D. Village society, district union and state federation
The Anand pattern has a producer-owned village dairy cooperative society, a district milk producers' union that owns chilling and processing plants, and a state cooperative milk marketing federation. Panchayats and banks are not tiers of it.
New Zealand's largest dairy cooperative, Fonterra, was formed in 2001 by:
A. A merger of the main dairy cooperatives with the national dairy board
Fonterra was formed by merging New Zealand Dairy Group, Kiwi Co-operative Dairies and the New Zealand Dairy Board. It remains farmer-owned, paying suppliers on milk solids.
Which is a core function of a village dairy cooperative society under the Anand pattern?
D. Collecting milk twice a day, testing it for fat and SNF, and paying producers on quality
The village society collects and tests milk, pays producers and supplies inputs such as feed, AI and first aid. Processing and marketing belong to the district union and state federation; licensing and inspection are regulatory functions of government.
Why do revolving credit lines suit dairy farmers' working-capital needs?
A. Feed and labour bills and milk income recur monthly, so a revolving limit matches the cash cycle
Dairy cash flow is continuous: costs and milk cheques recur through the year, so a revolving limit drawn and repaid as needed fits better than a single term loan.
Under the TRIPS Agreement, the minimum term of patent protection is:
B. 20 years from the filing date
TRIPS Article 33 sets a minimum of 20 years from filing. Fifty years after the author's death is a copyright term, not a patent term.
This plan follows where our questions actually fall, so the time goes where the marks are likely to be. It is our reading of the syllabus, not the exam body's weighting.
Read the manual chapters for these first and do every worked question you can find on them.
Aim for one sitting per unit, then mixed questions across them.
Learn the definitions, classifications and standard numbers; these units are more often recalled than worked.
Do these early in revision so they are fast on the day.
