Kudos for the right answer and explanation
The bottle is filled 80% to capacity, and then 70ml of rum makes the bottle 100% filled to capacity.
So,
70ml represents 20% of the capacity.
So,
BEFORE the rum was added, there were 280ml of liquid in the bottle (i.e., if 70ml represents 20% of capacity, then 280ml represents 80% of capacity)
We're told that 60% of the liquid is guava juice.
60% of 280ml = 168 ml
Answer: A
