Bīrūnī’s treatise on the rule of three and its variations, Maqāla fī rāshīkāt al-Hind, is an amalgam of Indian and Greek mathematics. He applies examples of Sanskrit origin and explains the rules based on the Greek theory of ratios. The printed Hyderabad version of the treatise is an uncritical copy of the only known manuscript, which has pages bound in an incorrect order. This is a study of the treatise, preliminary to producing a critical edition.
