Let x be the cost of pure milk.

∴ Cost of miture=x+25percent ofx=15

⇒x+ 25/100 * x =15

⇒ 100x+25x/100 =15

⇒125x =15×100

⇒x = 15×100/125 =Rs.12

Milk sold at Rs.15 is actually of Rs.12

∴Rs.16≡1lmilk

⇒ Rs.12≡ 1/16 ×12 liter milk = 3/4 liter milk and 1/4 liter of water

∴Milk:Water = 3/4 : 1/4 =3:1
