This is one of the six commentaries of Līlāvatī in Malayalam according to K V Sarma. It contains a problem on Uruḷ Paliśa, or what the text later explains as 'paliśakku paliśa'. The Malayalam term 'paliśa' translate as interest and 'paliśakku paliśa' translates to interest on interest [see r. 106 - r.109]. The text has a Sanskrit verse on how to solve the problem and gives detailed description in Malayalam. Compound interest is usually not found in any of the major texts such as Līlāvatī, Pāṭīgaṇitam, Kaṇakkatikāram, Ganitasarasangraham or in any Sanskrit Commentaries of Lilavati.
