120. O friend, subtract (the following) from 3: associated with of itself and with of this (assicuated quantity), associated with and of itself (in additive consecution), (similarly) associated with (fractions thereof) commencing with and ending with , and associated with of itself.

121. O friend, you, who have a thorough knowledge of Bhāgānubandha, give out (the result) after adding associated with of itself, associated with of itself, associated with of itself, associated with of itself, and associated with of itself.

Now the rule for finding out the one unknown (element) at the beginning (in each of a number of associated fractions, their sum being, given):--

122.[१] The optionally split up parts of the (given) sum, which are equal (in number) to the (intended) component elements (thereof), when divided in order by the resulting quantities arrived at by taking one to be the associated quantity (in relation to these component elements), give rise to the value of the (required) unknown (quantities in association).

Examples in illustration thereof.

123. A certain fraction is associated with and of itself (in additive consecution); another (is similarly associated with and of itself; and another (again is similarly associated) with and of itself; the sum of these (three fractions so associated) is 1: what are these fractions ?

124. A certain fraction, when associated (as above) with and of itself, becomes . Tell me, friend, quickly the measure of this unknown (fraction),

  1. 122. This rule will be clear from the working of example No. 123 as explained below:--
    There are three sets of fractions given and splitting up the sum, 1, into three fractions according to rule No. 75, we get and . By dividing these fractions by the quantities obtained by simplifying the three given sets of fractions wherein 1 is assumed as the unknown quantity, we obtain and and which are the required quantities.
