· It flows through Madhya Pradesh → Rajasthan → Gujarat.
· Due to its peculiar V-shaped course, it cuts the Tropic of Cancer once while entering Rajasthan and again while entering Gujarat.

· Luni is an inland river flowing mainly in Rajasthan.
· Sabarmati flows through Gujarat but crosses the Tropic only once.
