RAS question
The total length of the Aravalli Range is approximately:
Correct answer: (C) 692 km.
The Aravalli Range is approximately 692 km long from Palanpur in Gujarat to Delhi.
Explanation
The asked figure is the total length of the Aravalli Range, not only its Rajasthan stretch. The official Rajasthan Forest Department manual states that the range runs for about 692 km from Palanpur in Banaskantha district of Gujarat to Delhi. That matches option C. The 550 km figure is a trap: the range extends within Rajasthan from Sirohi to Khetri in Jhunjhunu district, which is a shorter state-level measure, not the full range. The broader description is consistent with the standard Rajasthan geography framing that places Guru Shikhar, 1,722 m, at Mount Abu as the highest peak of the Aravallis.
Why the other options are wrong
- (A) 550 km refers to the shorter Rajasthan stretch from the Gujarat border near Sirohi to Khetri, not the total Palanpur-to-Delhi length.
- (B) 850 km overstates the verified total length of about 692 km given by the Rajasthan Forest Department manual.
- (D) 480 km is below both the approximate total length of 692 km and the commonly tested Rajasthan stretch of about 550 km.
Concept
This tests the physical geography of Rajasthan, especially the extent of the Aravalli Range and the distinction between total length and the Rajasthan-only stretch. It recurs in RAS because the Aravallis shape standard questions on relief, districts, peaks and regional geography.
