41 That is to say, if x = d, y = ß is the minimum solution of the pulveriser WHEN THE INTERPOLATOR IS POSITIVE ax-c b = y, then the other solutions of the same pulveriser are X = mb + d y = ma + ß, where m = 1, 2, 3,.. Procedure for problems in which the given quantity is the part of the revolution to be traversed by a planet: 51. When the part (of the revolution) to be traversed by some (planet) is the given quantity, then (also) the same process should be applied, treating the part to be traversed as the addi- tive, or taking unity as the additive. All details of procedure are the same (as before). The pulveriser contemplated above is of the type ax + c b (1) According to the above rule, this is to be solved in the same way as ax- c b = y. ax 1 b = y, with the difference that wherever in solving (2) c is subtracted, in solving (1) it should be added. Or, the solution of (1) may be derived as before from the solution of = y.¹ (3) Example. "Given that 100 minutes of the eighth sign are to be traversed by the Sun, say quickly, after carefully considering, O intelligent one, if the Gunita of Äśmaka is known to you, all the years that have elapsed this day since the beginning of Kaliyuga. Also say the number of days that have elapsed since the beginning of Kaliyuga."2 ¹ It is also possible to reduce the pulveriser (1) to the form (2). For, when the part of the revolution to be traversed by a planet is given, the part traversed may be easily derived therefrom. 2 Bhaskara I's example, occurring in his comm, on Ā, ii, 32-33.
