सिद्धान्तशिरोमणि: गणिताध्याय (भास्कराचार्य - ग्रहगणित, मध्यमाधिकार व स्पष्टाधिकार सटीक)

62 in this Śuddhi we have subtracted the fractional part of the Kshayāhas for a different purpose so that in sub- tracting the Suddhi, we have increased the tithis by the fractional part of the Ksbayāhās. This increase there- fore should be nullified, which means that the quantity to be added is (x × 64/60) / 64 − x/60 = (x × 63/60) / 64 = (21/20) (x/64) = x (1 + 1/20) / 64 Hence the Kshepadinas or the tithis to be added to the number of tithis which have elapsed from the commence- ment of the Solar year, are x (1 + 1/20). This means that the ghaṭis x which form the fractional part of the Kshayāhas are to be increased by one twentieth part of themselves and are to be viewed as tithis and not ghaṭis as mentioned.
