Which one of the following rivers was earlier known as "Vitasta" ?

  1. A.Tista
  2. B.Jhelum
  3. C.Tungabhadra
  4. D.Bharatpuzha A - EDF-F-KJU

Correct answer

B. Jhelum

Explanation

The correct answer is B, Jhelum. The Jhelum was called the Vitasta in the Rig Veda and in later Sanskrit texts.

The rivers of the Punjab region carried Vedic names: Vitasta for the Jhelum, Asikni for the Chenab, Parushni for the Ravi, Vipasha for the Beas and Shutudri for the Satluj. The Jhelum rises at Verinag spring in the Kashmir Valley, flows through Srinagar and Wular Lake, and enters Pakistan to join the Chenab. The Greeks called it the Hydaspes, and the battle between Alexander and Porus in 326 BCE was fought on its banks.

A is wrong because the Tista is a Himalayan river of Sikkim and north Bengal that joins the Brahmaputra in Bangladesh.

C is wrong because the Tungabhadra is a tributary of the Krishna in Karnataka; Hampi stands on its bank.

D is wrong because the Bharatpuzha is a west-flowing river of Kerala, also called the Nila.

Exam tip: Vitasta, Jhelum; Asikni, Chenab; Parushni, Ravi; Vipasha, Beas; Shutudri, Satluj.

  1. A.A pesticide
  2. B.A manure that supplies nutrients to the soil
  3. C.A weedicide that kills the forest roots
  4. D.A means of levelling the slope
Show answer
Correct answer: B. A manure that supplies nutrients to the soil
