Q. Till which year, Calcutta was capital of India ?
Answer: 1911
Notes: Calcutta (now known as Kolkata) was the capital of India under British rule from 1772 to December, 1911. The British East India Company chose Calcutta as the capital of British India because of its strategic location and its access to the sea, which made it an ideal center for trade. During this period, Calcutta was a major center of commerce and industry, and it played a key role in the development of the British Empire in India. In 1911, the capital of British India was moved from Calcutta to Delhi.
