The rule for separating various capital amounts, on which the same interest has accrued, from their mixed sum :
60. Let the (given) mixed sum multiplied by the time (given) in relation to it be divided by the sum of that quantity, wherein are combined the various rate-capitals as multiplied by their respective rate times and as divided by their respective rate-interests. The interest (is thus arrived at); and (from this the capital amounts are arrived at an before.
Examples in illustration thereof. 61. The mixed sum (of the capital amounts lent out) at the rates of 2, 6 and 4 per cent per mensem is 4,400. Here the capital amounts are such as have equal amounts of interest accruing after 2 months. What are the capital amounts lent, and what is the equal interest) ?

(What are these amounts lent out and what is the interest ?)
The rule for arriving at the lent oat capital in relation to the known time of discharge by instalments:
63. Let the amount of the instalment as divided by the time thereof and as multiplied by the time of discharge be divided by
this, the capitals
