ALLIGATION AND MIXTURES

ALLIGATION AND MIXTURES

1.

C.P = [ S.P/(100+g) * 100 ]


2.Mean rate of interest,

R = [ (100*I)/P*T) ]


3.Final % of Alcohol =

[ (Qi/Pi)/(Qi+Qw added) ]

		Pi  ----->  Initial percentage

Qw -----> Quantity of water added


4.Final % of alcohol =





[ (Qi*Pi)/(Qi-Qw evoparated) ]


Qw -----> Quantity of water evoparated.


5.Quantity of water to be added =





[ Qmix * [(P2-P1)/(100-P2) ] ]


P1 and P2 are percentages of water.


6.Other than water =





[ Qmix * (P1-P2)/P2 ]


P1 and P2 are the % of constituent other than
water (i.e., salt,alcohol etc)


7.Ratio of water to milk =





g/100




8. Percentage of water =





[ (100*g)/(100+g) ]




9.





[ 1- (y/x) ]n * x


x -----> Capacity of container (or) Initial
quatity of pure milk.

y -----> Quantity drawn out each time.

n -----> No.of operations.


10.No.of rabits (4 legs) =





[ No.of legs given - (No.of heads given * 2) ]/2


No.of pigeons =





[ No.of heads given - No.of rabits ]



11. The mixture drawn out and replaced with water, so that the mixture may be       half water and milk is =

[ (1/2) * (difference in parts/greater part) ]


12.One gallon =

[ 100 litres ]
