Answer:
Shakuntala Devi (4 November 1929 – 21 April 2013) was an Indian mathematician, writer and mental calculator, popularly known as the "Human Computer". Her talent earned her a place in the 1982 edition of The Guinness Book of World Records. However, the certificate for the record was given posthumously on 30 July 2020, despite Devi achieving her world record on 18 June 1980 at Imperial College, London. Devi was a precocious child and she demonstrated her arithmetic abilities at the University of Mysore without any formal education.
On 18 June 1980, she demonstrated the multiplication of two 13-digit numbers – 7,686,369,774,870 × 2,465,099,745,779. These numbers were picked at random by the Department of Computing at Imperial College London. She correctly answered 18,947,668,177,995,426,462,773,730 in 28 seconds. This event was recorded in the 1982 Guinness Book of World Records. Writer Steven Smith commented, "the result is so far superior to anything previously reported that it can only be described as unbelievable."
Personal life
Devi returned to India in the mid-1960s and she married Paritosh Banerji, an officer of the Indian Administrative Service from Kolkata. They divorced in 1979 due to personal problems. In 1980, she contested the Lok Sabha elections as an independent candidate for Mumbai South and for Medak in Andhra Pradesh (now in Telangana). In Medak she stood against the former Prime Minister Indira Gandhi, saying she wanted to "defend the people of Medak from being fooled by Mrs. Gandhi"; she came ninth, with 6,514 votes (1.47% of the votes).] Devi returned to Bangalore in the early 1980s.
In addition to her work as a mental calculator, Devi was a notable astrologer and an author of several books, including cookbooks and novels. She started with writing short stories and murder mysteries, and had a keen interest in music.
