oops misread the puzzle, solution is correct, but solution/ puzzle could be worded better - though subtle i think adds some clarity
Having three bowls each partially filled with water.
Bowl A (8 litres capacity) has 5 litres of water.
Bowl B (5 litres capacity) has 3 litres of water.
Bowl C (3 litres capacity) has 2 litres of water.
Can you measure exactly 1 litre, pouring only 2 times?
1st Pour: Using Bowl A, fill Bowl C (which contains 2L of 3L capacity).
2nd Pour: Using Bowl C (which now contains 3L), fill Bowl B (which contains 3L of 5L capacity)
The two liters from removed from Bowl C to fill Bowl B will leave exactly 1 Liter.
possible other solution though could be difficult: empty Bowl A, place finger along edge of the middle of the edge of bowl C and pour with one stream going into empty bowl and other in to bowl B. Should give 1 liter. also if emptying doesn't count as pour could empty both A and B and get two bowl each with 1 liter. Making to equal size & shape holes at bottom of bowl would also split water well
