Solution:The correct answer is Aryabhatta-I, the 5thcentury Indian mathematician and astronomer, who developed an alphabetic numeral system for use in his astronomical and mathematical calculations.
In the Gîtika Padam chapter of his seminal work Aryabhatiya, he introduced a system where:
• Consonants represented digits from 1 to 9 and multiples of 10.
• Vowels represented place values (powers of ten: 1, 100, 10,000, etc.).
This combination allowed for large numbers to be encoded compactly using Sanskrit syllables, making them easier to memorize and transmit in verse form - an essential method for preserving scientific knowledge at the time.
