∴ Mixture sold for Rs. 125
= = litres
∴ Quantity of mixture = litres
∴ Quantity of milk = 1 litre
∴ Quantity of water = - 1 = litre
∴ Required ratio = : 1 = 1 : 4
Solution:
Cost price of 1 litres of milk = Rs. 100∴ Mixture sold for Rs. 125
= = litres
∴ Quantity of mixture = litres
∴ Quantity of milk = 1 litre
