An example in illustration thereof.
155 and 156. The original price of one piece of sandalwood and one piece of agaru wood, they being together 20 palas (in weight), is 104 paņas; when after a time they were sold with their prices mutually altered, 116 paņas were obtained.

The rule for arriving at the distance in yōjanas travelled by the horses of the sun's chariot when yoked as desired:-
157. The number representing the total yōjanas, divided by the total number of horses, gives the yōjanas (which each has at a stage to travel) in turn. These yōjanas multiplied by the optionally chosen number of horses to be yoked, give the measure of the distance to be travelled over by each horse.
An example in illustration thereof.

The rule for arriving at the value of the commodity to be found in the hands of each (of a body of joint proprietors}, from the conjoint remainder left after subtracting whatever is desired from the total value of all the commodities:--
159. Let the sum (of the values of the conjoint remainders) of the commodities be divided by the number of men lessened by one; the quotient will be the total value of all the commodities (owned in common). This total value as diminished by the specified values gives (in the corresponding cases) the value of commodity in the hands (of each of the proprietors in turn).
An example an illustration thereof.
