Which of the following is not an Indian Mathematician ?

Question

Accepted Answer

Option 4, Pythagoras, is the correct answer because Pythagoras was not an Indian mathematician. He was a Greek philosopher and mathematician who lived around 570–495 BCE. Pythagoras is best known for the Pythagorean theorem, which relates to the sides of a right triangle. His contributions were primarily in the realm of mathematics and philosophy in ancient Greece.

Now, let's explain why the other options are incorrect:

1. **Ramanujan**: Srinivasa Ramanujan was an Indian mathematician who made substantial contributions to mathematical analysis, number theory, infinite series, and continued fractions. He was born in 1887 in Erode, India, and is celebrated as one of the greatest mathematicians in Indian history.

2. **Brahmagupta**: Brahmagupta was an Indian mathematician and astronomer who lived in the 7th century. He is known for his work on arithmetic, algebra, and astronomy. His most famous work, the "Brahmasphutasiddhanta," contains early concepts of zero and rules for arithmetic operations involving zero.

3. **Aryabhatta**: Aryabhatta was an ancient Indian mathematician and astronomer who lived in the 5th century. He is known for his work "Aryabhatiya," which covers a wide range of topics, including mathematics and astronomy. Aryabhatta made significant contributions to trigonometry and algebra.

In summary, Options 1, 2, and 3 are incorrect because Ramanujan, Brahmagupta, and Aryabhatta were all prominent Indian mathematicians who made significant contributions to the field. Option 4, Pythagoras, is the correct answer as he was a Greek mathematician, not Indian.
