Four friends, Ritu, Kabir, Shilpa, and Aditya, travelled to a city in April on dates 4, 11, 18, and 25. Kabir went exactly one week before Shilpa. Aditya did not go on the 25th. Ritu travelled after Shilpa. Aditya travelled on the 18th. Who travelled on the 11th?
Show answer & explanation
Correct answer: C
Explanation
Given dates: 4, 11, 18, and 25 April (each exactly 7 days apart).
• Aditya: Travelled on the 18th.
• Kabir and Shilpa: Kabir went exactly one week (7 days) before Shilpa. The only available pair of consecutive dates where both are free is 4th and 11th. Thus, Kabir went on the 4th and Shilpa went on the 11th.
• Ritu: Travelled after Shilpa, so Ritu travelled on the remaining date, the 25th.
Final arrangement:
• 4th April: Kabir
• 11th April: Shilpa
• 18th April: Aditya
• 25th April: Ritu
Therefore, Shilpa travelled on the 11th.
