Problem:Let there are two cone.one contains 1 litre milk and other contain 1 litre water.if i take one cup milk from first and droped into second.then again i took one cup mixture from seecond and droped into first one.
Is the amount of milk in first is same as amount of water in second?
let amount of liquid in cup is c.
cane 1 cane 2
Water 0 1
milk 1 0
water 0 1
milk 1-c c
conc^n of milk in second cone is c/(1+c) and of water 1/(1+c)
in one cup amount of milk =c* c/(1+c) amount of water c/(1+c)
water c/(1+c) 1-c/(1+c)=1/(1+c)
milk 1-c+c*c/(1+c)=1/(1+c) c-c*c/(1+c)=c/(1+c)
