1.
C.P = [ S.P/(100+g) * 100 ] 
2.Mean rate of interest,
3.Final % of Alcohol =
[ (Q_{i}/P_{i})/(Q_{i}+Q_{w added)} ] 
P_{i} > Initial percentage
Q_{w} > Quantity of water added
4.Final % of alcohol =
[ (Q_{i}*P_{i})/(Q_{i}Q_{w} _{evoparated}) ] 
Q_{w} > Quantity of water evoparated.
5.Quantity of water to be added =
[ Q_{mix} * [(P_{2}P_{1})/(100P_{2}) ] ] 
P_{1} and P_{2} are percentages of water.
6.Other than water =
[ Q_{mix} * (P_{1}P_{2})/P_{2} ] 
P_{1} and P_{2} are the % of constituent other than water (i.e., salt,alcohol etc)
7.Ratio of water to milk =
8. Percentage of water =
9.
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 =
