The motif of Hampi with a stone chariot is printed on the reverse side of which Indian currency note of the Mahatma Gandhi new series?

Introduction / Context:
Indian currency notes in the Mahatma Gandhi new series carry different motifs on the reverse side that depict India's cultural heritage, natural beauty and scientific achievements. Examinations often ask which scene appears on which denomination. This question focuses on the note that has the famous stone chariot of Hampi printed on the reverse.

Given Data / Assumptions:
- The question refers to the motif of Hampi with a chariot on the reverse of an Indian currency note.
- The options list four denominations: 100, 1000, 50 and 500 rupees.
- We assume the learner has seen or studied pictures of the post demonetisation series of notes introduced by the Reserve Bank of India.

Concept / Approach:
In the Mahatma Gandhi new series, the fluorescent blue Rs 50 note features the stone chariot of Hampi, a UNESCO World Heritage site in Karnataka, on its reverse. Other denominations have different motifs: for example, the Rs 500 note shows the Red Fort and the Rs 2000 note shows Mangalyaan. The Rs 1000 note is no longer in circulation and did not belong to the new series.

Step-by-Step Solution:
Step 1: Recall images of the new series notes. The blue Rs 50 note stands out with the Hampi chariot image. Step 2: Remember that the Rs 500 note from the new series has a picture of the Red Fort with the national flag. Step 3: The old Rs 100 note had a different design and does not feature the Hampi motif in the new series. Step 4: The Rs 1000 note was withdrawn during demonetisation and was not part of the new series introduced later. Step 5: Therefore, identify the Rs 50 note as the one that carries the Hampi chariot motif.

Verification / Alternative check:
You can verify by looking at a current Rs 50 note or by checking Reserve Bank of India descriptions of currency designs, which explicitly state that the reverse depicts Hampi with a chariot. General knowledge books on Indian currency also provide tables linking each denomination of the new series with its associated motif, confirming that Rs 50 corresponds to Hampi.

Why Other Options Are Wrong:
Rs 100 note: The new violet Rs 100 note shows the Rani ki Vav stepwell in Gujarat, not Hampi.

Rs 1000 note: This denomination has been withdrawn and did not form part of the Mahatma Gandhi new series with the same motif scheme.

Rs 500 note: The new stone grey Rs 500 note features the Red Fort on the reverse side, representing India's historical monument in Delhi.

Common Pitfalls:
Learners sometimes mix up the motifs associated with Rs 50 and Rs 100 notes because both depict heritage sites. Another error is to choose denominations that no longer exist, such as Rs 1000, based on older memory. A simple revision strategy is to make a small table of denominations and motifs and revise it periodically before exams, paying special attention to notes introduced after demonetisation.

Final Answer:
The motif of Hampi with a stone chariot appears on the reverse of the Rs 50 note of the Mahatma Gandhi new series.
