Answer:
4%
Step-by-step explanation:
Amount of acid initially = 96/100 * 1000
= 960 ml
First, 1/4 acid is taken out,
So now amount of acid = 1/4 * 960
= 240 ml
Then, 1/6 of acid is taken out,
So now amount of acid = 1/6 * 240
= 40 ml
So, 40 ml is acid and the rest is water.
Therefore, the percentage of the acid is 4%.
