# A solution of salt and water contains 30% salt, 225 liter water is evaporated and now percentage of salt in solution becomes 60%. find the initial quantity of solution?

A. 750 litre

B. 300 litre

C. 500 litre

D. 450 litre

A. 750 litre

B. 300 litre

C. 500 litre

D. 450 litre

Initial Salt = 30% of X = 0.30X.

Initial Water = 70% of X = 0.70X.

250 liter of water evaporated.

So, Final water = (0.70X - 225).

Now, salt rises to 60% of the mixture, it means as water dried up salt rises.

Now, Total Mixture = (0.70X -225 + 0.30X).

Final salt = 60% of(0.70X - 225 + 0.30X)

As,

0.3X = 60% of(0.70X - 225 + 0.30X)

0.3X = 0.6X - 135.

Or, 0.3X = 135.

Thus, X = 450.
