In a milk solution of 10 lit, 2 lit of water is added thereby the concentration of milk is reduced by 15%. What is the quantity of milk in the solution?
I tried:
Concentration - Water added - Milk:
100 - 0 - 10 liter
85 - 0 - ?
\frac {85\times10}{100} = 8.5
But Answer is 9 litres. Please tell how to solve this problem?
