----------------------------------------------------------------------

= 0.18.

Numerator is the amount of the soluted sugar, x is a volume of the 10% solution.

0.1x + 0.3*(50-x) = 0.18*50,

0.1x - 0.3x = 9 - 15,

-0.2x = -6,

x = = 30.

Answer. 30 liters of 10% solution and 50-30 = 20 liters of 30% solution.
