Question

One salt solution is 20% salt and another is 60% salt. How many cubic centimeters of each solution must be mixed to obtain 100 cubic centimeters of a 30% salt solution?

Answer 1

Answer:

75 and 25 cubic centimetre

Step-by-step explanation:

20% 60%

\ /

30%

/ \

30 : 10

which is,

3 : 1

Hence, 3/4 parts of resultant volume is solution I

and 1/4 parts of resultant volume is solution II

3/4 of 100 = 75

1/4 of 100 = 25
