Indian Basket

Indian Basket is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Indian Basket rather than just read about it. In short: Indian Basket (IB), also known as Indian Crude Basket, is weighted average of Dubai and Oman (sour) and the Brent Crude (sweet) crude oil prices. It is used as an indicator of the price of crude imports in India and Government of India watches the index when examining domestic price issues.

Key takeaways

Indian Basket belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Indian Basket to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Indian Basket from memory before moving on to harder problems.

Reference excerpt

Indian Basket (IB), also known as Indian Crude Basket, is weighted average of Dubai and Oman (sour) and the Brent Crude (sweet) crude oil prices. It is used as an indicator of the price of crude imports in India and Government of India watches the index when examining domestic price issues.

Methodology for calculation The Indian basket of Crude Oil represents a derived basket comprising Sour grade (Oman and Dubai average) and Sweet grade (Brent Dated) of Crude oil processed in Indian refineries. During the year 2018-19, the ratio is 75.50 : 24.50 (Dubai : Brent respectively) and during the year 2017-2018, the ratio was 74.77 : 25.23 (Dubai : Brent). The Indian Basket is weighted average of daily prices and is updated daily on the website of the Petroleum Planning and Analysis Cell of the Ministry of Petroleum and Natural Gas.

Worked examples

Example 1 — a first encounter with Indian Basket

Start with the simplest possible case. Write down what Indian Basket claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Indian Basket before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Indian Basket ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Indian Basket

In research: Indian Basket appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Indian Basket in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Indian Basket is common in secondary-school and first-year university syllabi. It links to neighbouring topics Benchmark crude oils, Economy of India, Petroleum, so understanding it makes those chapters shorter.
In everyday life: Look for Indian Basket outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
