RAS question

Aryabhata, the famous mathematician and astronomer of the Gupta age, authored which text?

Correct answer: (B) Aryabhatiya.

Aryabhata, the Gupta-age mathematician and astronomer, authored the Aryabhatiya.

  1. (A)

    Pancha Siddhantika

  2. (B)

    Aryabhatiya

  3. (C)

    Surya Siddhanta

  4. (D)

    Lilavati

Explanation

Aryabhata is linked with the Aryabhatiya, composed in 499 CE. It is credited with major work in algebra and trigonometry, the idea that the Earth rotates on its axis, and a value of pi as 3.1416. The National Council of Educational Research and Training (NCERT) independently supports the link by noting that the first use of sine in the modern sense appeared in Aryabhata's Aryabhatiyam around A.D. 500. Aryabhatiya alone combines Aryabhata's authorship with the mathematical-astronomical tradition of Gupta-age science.

Why the other options are wrong

  • (A) Pancha Siddhantika is associated with Varahamihira, not Aryabhata.
  • (C) Surya Siddhanta is an astronomical tradition, but Aryabhatiya/Aryabhatiyam is the work associated with Aryabhata.
  • (D) Lilavati is associated with Bhaskara II, not Aryabhata.

Concept

Ancient India author-text linkage for Gupta-age science centers on named scholars, texts, and contributions in mathematics and astronomy. RAS often tests a single scholar, work, and contribution directly.
