Expert Answer:

Let X be the amount of first solution and Y be the amount of second to be taken.

The amount of acid in X = 0.5X

But another 50% has to be water.

The amount of water = 0.5X.

The amount of acid in Y = 0.25Y

The amount of water in Y = 0.75Y

The total amount of acid required in final solution = 0.4x10 = 4 lit and remaining 6 lit would be water.


0.5X + 0.25Y = 4 .............(1)

Similarly for water,

0.5X + 0.75Y = 6  .................(2)

Solving (1) and (2), gives,

Y = 4 lit and X = 6 lit.

6 lit of first solution and 4 lit of second solution should be taken.
