Devendra Marghade  (10 years ago)

50%
Quantity after adding 20% water=1.2 liter
SP of 1.2 lit.@15 Rs./liter=15*1.2=18 Rs
CP=12 Rs/lit.
% profit=100*(18-12)/12=50

Before mixing
------------
Cp of 1L milk= Rs 12

20% water is mixed , so new vol = 1200 mL

since water is free of cost so CP of 1L milk = Rs 10
A/Q
it is being sold @ Rs15 .
Hence profit = 50%

He buys it for 12 Rs. Adds water20 %. So cost of mixture is 12.00.
Sells it for 15 RS. So profit is 15-12 = 3 Rs.
Percentage of profit is (3/12)X 100 = 25%

NB: Sells it for 15rs not sells it for 15rs per lt.

subramani  (10 years ago)

after 20% sell rate (1.2l) = Rs.15/-
so for 1l= 15/1.2
= 12.50
Actual rate for 1l= Rs.12/-
Gain= 12.50-12=.50
% of gain = .50/12 x100=4.166%

Ans = 50%
1 litre cost = Rs 12
now 20% water is added,so 1.2L cost price becomes rs 12
C.P of 1 L Milk=Rs(12/1.2)=Rs 10
Given,S.P of 1L Milk= Rs 15
Profit=Rs(15-10)=Rs 5

Therefore, %age gain=(profit/C.P)*100=(5/10)*100=50% (Ans)

Medha Mitra  (10 years ago)

Let us take 1 liter of milk as 100%. So price of 100% of milk is Rs.12.
Now if in the mixture of milk and water, 20% of the mixture is water, then 80% must be milk. And as 100% of milk is Rs. 12, then 80% of milk must cost (80*12)/100=Rs. 9.6
Now, when the mixture is sold at Rs. 15, then the gain is Rs.(15-9.6)= Rs. 5.4
Therefore, the percentage gain= (5.4/12)*100% = 45%

45%
100% milk is for 12rs
there4 80% for 9.6rs
sp=15rs
there4 gain =15-9.6
=5.4rs/-
%gain = 5.4/12*100= 45%

nitu  (10 years ago)

let the milk is 100liter , than the cost prize will be 100*12=1200
if we mix 20%water than the milk will be 120 liter having cp=1200
and given the sailing prize is 15 rs per liter than it is sp=1800
gain%=100*(1800-1200)/1200=50%

bhasker gupta  (10 years ago)

for 1tr=15/-
therefore for 1.2ltr(since,20% water)=1.2*15=18/-
now gain=(sp-cp)/100cp=(18-12)/100*12=50% ans.....

Aamir Sohail  (9 years ago)

gain=15/1200-12/1000=5*10^(-4)
%=gain/c.p*100
=5*10^(-4)/(12/1000)*100
=4.166%

Sudhanthira Ramalingam  (9 years ago)

A man buying 1ltr milk for 12 rs then he is adding up the water to 20% and therefore selling it for 15.So cp=12 and sp=15 sp-cp=gain... gain =3 .. gain%=(3*100)/12 is 25%
