Ganitashastra (Mathematics and Algebra)

Source: Hindu Mathematics

Trairāśika (त्रैराशिक) refers to the “rule of three” and represents one of the twenty operations (logistics) of pāṭīgaṇita (“science of calculation which requires the use of writing material—the board”), according to Pṛthudakasvāmī’s commentary on the Brāhmasphuṭasiddhānta by Brahmagupta, a Sanskrit treatise on ancient Indian mathematics (gaṇita-śāstra) and astronomy from the 7th century.—The Hindu name for the Rule of Three terms is trairāśika (“three terms”, hence “the rule of three terms”). The term trairāśika can be traced back to the beginning of the Christian era as it occurs in the Bakhshali Manuscript, in the Āryabhaṭīya and in all other works on mathematics. About the origin of the name Bhāskara I (c. 525) remarks: “Here three quantities are needed (in the statement and calculation) so the method is called trairāśika (‘the rule of three terms’)”.

The Rule of Three (trairāśika) was highly appreciated by the Hindus because of its simplicity and its universal application to ordinary problems. The method as evolved by the Hindus gives a ready rule which can be applied even by the “ignorant person” to solve problems involving proportion, without fear of committing errors.

Āryabhaṭa I in the Āryabhaṭīya: “In the Rule of Three, the phala (‘fruit’), being multiplied by the icchā (‘requisition’) is divided by the pramāṇa (‘argument’). The quotient is the fruit corresponding to the icchā. The denominators of one being multiplied with the other give the multiplier (i.e., numerator) and the divisor (i.e., denominator)”.

Brahmagupta in the Brāhmasphuṭasiddhānta: “In the Rule of Three pramāṇa (‘argument’), phala (‘fruit’) and icchā (‘requisition’) are the (given) terms; the first and the last- terms must be similar. The icchā multiplied by the phala and divided by the pramāṇa gives the fruit (of the demand)”.

Śrīdhara in the Triśatikā: “Of the three quantities, the pramāṇa (‘argument’) and icchā (‘requisition’) which are of the same denomination are the first and the last; the phala (‘fruit’) which is of a different denomination stands in the middle; the product of this and the last is to be divided by the first”.

Mahāvīra in the Gaṇitasārasaṃgraha: “In the Rule of Three, the icchā (‘requisition’) and the pramāṇa (‘argument’) being similar, the result is the product of the phala and icchā divided by the pramāṇa”.

Āryabhaṭa II (950) in the Mahāsiddhānta: “The first term is called māna, the middle term vinimaya and the last one icchā. The first and the last are of the same denomination. The last multiplied by the middle and divided by the first gives the result”.
