Rupee is the currency of India. In the same international currency analogy, Yen is the currency of which country?

Introduction / Context:
This analogy question belongs to the general knowledge category covering world currencies and countries. The first pair Rupee : Indian indicates that the rupee is the currency used in India. The second pair Yen : ? asks you to identify the country whose currency is the yen. Such currency based analogies are standard in competitive exams as they test basic awareness of international economic facts and simple one to one relationships.

Given Data / Assumptions:

• Rupee is the official currency of India.
• Indian refers to something that belongs to or is related to India.
• Yen is a well known foreign currency.
• The options are Pakistan, Turkey, Japan, and Bangladesh.
• We assume basic knowledge of widely used world currencies.

Concept / Approach:
The relationship being tested is clear and simple: currency to country. Rupee corresponds to India, and in the same way yen corresponds to Japan. The Japanese yen is one of the major currencies traded internationally, and the word yen is strongly associated with Japan in news, finance, and textbooks. None of the other options Pakistan, Turkey, or Bangladesh uses yen as its currency. They use rupee or lira or taka instead. Therefore, the correct completion for the pair is Yen : Japan.

Step-by-Step Solution:
Step 1: Note that the rupee is the currency of India. Step 2: Recognise that the analogy is currency to country, not language or any other relation. Step 3: Recall which country uses the yen as its currency. Step 4: Remember that Japanese yen is frequently mentioned in international trade and exchange rate discussions. Step 5: Look at the options Pakistan, Turkey, Japan, and Bangladesh. Step 6: Select Japan, because yen is the currency of Japan and not of the other listed countries.

Verification / Alternative check:
We can verify by listing some other common currency associations. Pakistan uses the Pakistani rupee, Bangladesh uses the Bangladeshi taka, and Turkey uses the Turkish lira. Japan uses the Japanese yen. News about currency markets often mentions the dollar, euro, pound, and yen as major currencies. Whenever yen is mentioned, it is tied to Japan. This consistent association confirms that Japan is the correct answer and maintains the same pattern as rupee and India in the first pair.

Why Other Options Are Wrong:
Pakistan: The national currency of Pakistan is the Pakistani rupee, not the yen. Turkey: Turkey uses the Turkish lira as its currency, so yen does not belong to Turkey. Bangladesh: Bangladesh uses the taka as its currency, which is called Bangladeshi taka in full, not yen.

Common Pitfalls:
Most candidates who recognise the word yen will choose Japan immediately. However, some may confuse currencies if they are not familiar with current affairs. Others may overthink and consider regional proximity, but currency names are very specific and do not follow regional patterns. The best strategy is to memorise a core list of country currency pairs, such as rupee India, yen Japan, dollar United States, euro Eurozone, and so on, which will make questions of this type very easy in exams.

Final Answer:
Rupee is the currency of India, and in the same way yen is the currency of Japan, so Japan is the correct answer.
