An example in illustration thereof.

88. In this (problem), the (given) capitals are 40, 30, 20 and 50; and the months are 5, 4, 8 and 6 (respectively). The sum of the amounts of interest is 34. (Find out each of these amounts.)

The rule for separating the various capital amounts from their mixed sum:-

30. Let the quantity representing the mixed sum of the various capitals lent out be divided by the sum of those (quotients) which are obtained by dividing the various amounts of interest by their corresponding periods of time and let the (resulting) quotient be multiplied (respectively) by (the various) quotients obtainod by
