Allegation meaning
Allegation means mixing two or more ingredients in some ratio.
The key points from this topic of applied mathematics are:
1. To find ratio in which 2 or more ingredient at the given prices must be mixed to produce a mixture at desired price
D – Dear price
mp – Mean price
C – Cheap price
2. For repeated dilution
To find the pure quantity of a liquid left after the ‘n’ number of repeated dilution, we use one formula.
If a vessel contains ‘x’s units of a liquid from which y units are taken out and replaced by water. After ‘n’ number of repeated dilution, the quantity of pure liquid :
in units.
Remember; ‘n’ is generally taken as +1, for example; if in the question it is written 2 more times, then we take n as 2+1 which is 3.
