• statement 1 is sufficient.
  15 litre of milk(water + milk) = cp of 15 litre of milk
  CP of 1 litre=x
  80% of 15 litre =12 litr of milk.
  12 litr of milk sold at 15x
  (15x-12x)*100/12x
  25%.

• 1 litre CP =Rs 16
  Now 20% water added,means 80% milk remaining ie 8/10 litre
  8/10 lit sp=16rs(given)
  1 lir =20rs
  Profit=sp-cp=20-16=4rs
  profit%=(4*100)/16=25%

• 20% is water
  means 80% of 15 litres is milk= 80/100*1=12 litre
  cost price of 15 litres= selling price of 12 litres
  let c.p of 1 litre= 1 rupee
  cost price of 12 litres=12 rps
  selling price of 12 litres=15 rps
  profit=(s.p-c.p)*100/c.p
  =3/12*100=25%

• The answer of the statement can be obtained by combining both the statements together
• 11 years agoHelpfull: Yes(2) No(23)
• The question is saying that adding 20% of water.(not given quantity). Read it carefully nitish :)
• 11 years agoHelpfull: Yes(1) No(0)
• ans can be obtained by the only 1st there is no need of second statement
  cost let be: X
  
  20% of 15 = 3
  means there is 12 ltr milk and 3 ltr water
  so
  12 ltr mlk has ------------------------- 3 ltr wtr
  then
  1 ltr mlk would the amount of water---- 3/12 ltr = 1/4ltr
  
  when seller selling 1 ltr milk at price X rs
  while he paying only for that only 3X/4 rs
  So there would be profit of X/4 rs
  
  Prft %= ((X/4)/3X/4)*100= 33.33%

• @vidushi
  when you wrote "8/10 lit sp= 16 rs(given)"
  you became wrong as you made water:milk = 200:800 = 1:4
  but it is clear from question that in 1000 ml(1 lit.) we add 20% of water i.e.
  water:milk = 200:1000 = 1:5
  so, Actually correct solution will be...
  20% of 15 lit = 3 lit.
  we get 3 lit extra.
  As the cp is same as sp so, let's say cp is rs 1/lit
  so total cp =15
  and total sp =18
  %profit (3/15)*100 = 20%

• not able to understand the question is it saying that add 20% of given quantitiy...
  if it is that then
  let 100 litres be sold at 100 rup.
  then adding 20% percent 120
  120-100=20
