Answer 1

Do you know algebra?

I am thinking he bought x liters of milk
he added 5 L of water: (x+5)
he sold it for Rs 10, so 10(x+5)
the ratio of selling/cost to buy is
\[ \frac{10(x+5)}{10x}= \frac{5}{4} \]

Answer 2

you solve for x, and then x+5 for the answer

Answer 3

x=20

Answer 4

yes, so the amount of mixture (x+5) is 25 L

Answer 5

thanx!
