Which of the following Indian mathematicians are known as founders of 'numerical analysis' ?
(i) Ramanujan (ii) Bhaskaracharya
(iii) Varahmihir (iv) Aryabhatta
Choose the correct option.
Answer: A
The key is (i) and (iii), Ramanujan and Varahmihir. I could not confirm this from a standard reference, and nothing I found shows it wrong.
The only answer I found for this item is a coaching site that gives the same key, and its reasoning is thin: it links Varahmihira's astronomical calculations and Ramanujan's rapidly converging series for pi to approximation methods, which are the business of numerical analysis. 'Founder of numerical analysis' is not a standard historical attribution for any of the four, so the question depends on the examiner's source.
The other options pair Bhaskaracharya or Aryabhatta with another name. Both are famous for important mathematical work (Aryabhatta for his Aryabhatiya and sine tables, Bhaskaracharya for the Lilavati and Bijaganita), but they are not named as the founders in the keyed answer. The explanation here records the Board's key and the reservation, and does not claim more than that.
