a milkman makes a profit of 20% on the sale of milk. If he were to add 10% water to the milk, by what % would his profit increase?

• let he sells 100 lit of milk @ 120 rs. means his cost price must b 100 to gain 20% profit.
  Nw he adds 10% milk ie total milk z 110 lit.
  Now he will get 132 rs. by selling 110 lit f milk (120*110/100)
  total profit = 32 rs
  increased profit =12 rs
  %age increase= 12/20= 60 %

• if he sells for rs.100 he gets profit of rs.20 by adding 10% water he adds 10rs milk (consider)
  total money of milk rs.110
  profit 20% = 22 rs
  old profit = 20 rs
  increase in profit = 22/20=11%

• above all answers are wrong
  here the formula is a+b+(ab)/100= 20+10+200/100= 32%

• Initial Profit - 20%
  Milkman adds 10% water which is also profit for him.
  Net or effective profit = a+b+(ab/100).
  i.e.., 20+10+(20*10/100) = 20+10+2 = 32%

• intially milk =10l
  so profit of 20% means 120/100*10=12
  next 10% 0f water is added so i L of water added to the whole solution (i.e 10/100=1:10=water:milk)
  all in all the new solution is 11L
  so 20%profit now means 120/100*11=13.2
  net profit=(13.2-12)/12*100=10
  so ans is [10]

• The milk man's profit increase is 32%.
  
  Solution:
  
  = x + y + xy / 100
  
  = 20 + 10 + (200 / 100)
  
  = 32%
