Allegation and Mixture
Allegation and Mixture, applied mathematics, class XII, CBSE. Only important aspects of this topic are discussed.
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 :
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.
