Brihat Parashara Hora Shastra
भागादिकहतादेष्यात् त्रिंशल्लब्धयुता लवाः । स्वमृणं तुलमेषादौ शनीन्द्वोश्च त्रिराशिषु ॥ १६॥
The degrees etc. of the Bhuja should be multiplied by the figure, corresponding to the highest of the left out Khandas and divided by 30. Add the resultant product to the sum, obtained earlier. Convert this to Rāśi, degrees, minutes and seconds. If Candr and Śani are in Tula, or ahead, add to this 3 Rāśis and, if in Mesh to Kanya, reduce from this 3 Rāśis.
