if the man buys 1litre milk for rs.12 means 800millilitre of milk is Rs.9.6
he add 800ml with water so he gained Rs.5.4 other 200ml is Rs.2.4
so he sell the milk of 1lit by Rs.17.4
so the percentage is (5.4*100/12)=45%

cp=1*12=12
sp=1.2*15=18
gain=sp-cp=6
gain%=(6/12)*100=50%

20% OF 1000 ml =200 ml, so C.P of (1000+200) ml is 12 rs. , now C.P of 1ltr milk=(12*1000)/1200 = 10, so profit=15-10=5, gain % =(5/10)*100 = 50 %

Considering the fact that he buy the milk at Rs 12 and sells it at Rs 15 , we need not to calculate the % of milk and water as we are asked the %gain. (SP=15 & CP= 12) => profit = Rs 3
and hence (Rs 3 / Rs 12)% = 25%.

Here selling price of milk is 15 rs. and cost price of milk is 12 rs. so the formula to calculate gain =(sp-cp)/cp*100
(15-12)/12*100=25%

after added with water milk % is .8L so 0.8*12=9.6
so gain=15-9.6=5.4
gain%=5.4/9.6*100 = 56.25%

SP = 15 rs , CP =12 rs profit=SP-CP
=15-12
=3 rs
profit%=profit/cp*100
= 3/12*100= 25% gain Ans
