Q. Mumbai was originally formed from how many islands before merging into a single landmass?
Answer: Seven
Notes: Mumbai originally consisted of seven islands: Isle of Bombay, Colaba, Old Woman's Island, Mahim, Mazagaon, Parel, and Worli. These islands were joined by land reclamation completed by the British in the 19th century, forming present-day Mumbai, Maharashtra's capital and India's financial hub.
