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

Let the capacity of bottle be X mL
20% of X = filled with 70 mL of Rum = 0.20X
70 = 0.20X
X = 350 mL
80% of X = (Guava + Pineapple) juice = 0.80X
60% of 0.80X = Guava = 0.48X = 0.48 x 350 = 168 mL
Hence, option A
20% of X = filled with 70 mL of Rum = 0.20X
70 = 0.20X
X = 350 mL
80% of X = (Guava + Pineapple) juice = 0.80X
60% of 0.80X = Guava = 0.48X = 0.48 x 350 = 168 mL
Hence, option A
