Answer 1

Your answer is D) 24.3 L

Answer 2

Answer:

it is option D 24.3L

Step-by-step explanation:

1 st liquid contains 30L of water

2nd liquid contains 27 L of water because 10 percent of the liquid is replaced

here again in 3rd liquid 10 percent should be replaced

so,10 percent of 27 is 2.7

so,27-2.7=24.3
