In this word puzzle, the phrase rhythm of eyes is a clue for which Indian city name?

Introduction / Context:
This question is a classic example of an English plus Hindi word puzzle, where a short strange phrase hides the name of a well known Indian city. The phrase rhythm of eyes does not look like a normal geographical clue, but if you break it into parts and relate it to Hindi vocabulary, you can decode the answer. Such puzzles are used to test lateral thinking and your ability to connect sounds and meanings across languages.

Given Data / Assumptions:
• The phrase given is rhythm of eyes.
• We are told that the answer is the name of a city in India.
• The options are Chennai, Nainital, Srinagar and Karnataka.
• We may assume that rhythm can be connected with the Hindi word taal or tal, and eyes can be linked with the Hindi word nain or naina.

Concept / Approach:
The basic idea is to translate or map the English words eyes and rhythm into approximate Hindi words and then see if they combine to form a city name. In Hindi, nain or naina means eyes. The word taal or tal can refer to rhythm in music, but it can also mean lake. When we join naini or nain with tal, we get Nainital, a hill station in Uttarakhand. So rhythm of eyes becomes tal of nain, that is Nainital. The approach is therefore sound based wordplay using Hindi vocabulary.

Step-by-Step Solution:
Step 1: Identify that eyes can correspond to the Hindi word nain or naina. Step 2: Recognise that rhythm can be connected with taal or tal, which is often used in Indian music to describe beats and rhythm. Step 3: Consider city names in India that contain both a nain element and a tal or taal element. Step 4: Notice that Nainital is made of Naini (eyes) plus tal (lake or rhythm in this puzzle context). Step 5: Conclude that rhythm of eyes is a playful way to suggest Nainital, making it the correct answer among the options.

Verification / Alternative check:
We can verify by checking the other options. Chennai and Srinagar do not split naturally into meaningful Hindi words that match eyes and rhythm. Karnataka is a state, not a city, and also does not fit the wordplay. Only Nainital clearly contains naini (eyes) and tal (which can be linked with rhythm or lake). Also, many puzzle books explicitly list rhythm of eyes as the clue for Nainital, which confirms that this mapping is standard and intentional rather than a coincidence.

Why Other Options Are Wrong:
• Chennai: A major city in Tamil Nadu, but its name does not contain elements that correspond to eyes or rhythm in Hindi or English.
• Srinagar: Capital city of Jammu and Kashmir, but again no obvious connection with the words eyes and rhythm in the puzzle sense.
• Karnataka: It is an Indian state, not a city, and its name does not break into parts that match the clue words in either English or Hindi.

Common Pitfalls:
Students often try to over analyse the English words and search for cities associated with dance, music or eye hospitals. Others ignore the hint that the city name is Indian and look for a direct English phrase. The trick is to notice that many Indian city puzzles use Hindi word fragments hidden inside English sounding clues. Remembering that nain equals eyes and tal or taal can stand for rhythm or lake helps unlock many similar word puzzles in exams and interviews.

Final Answer:
The phrase rhythm of eyes is a word puzzle clue for the Indian hill station Nainital.
