A container of milk was 4/5 full. When 12 bottles of milk were taken out and 8 bottles of milk were poured into it, it was 3/4 full. How many bottles of milk can the container contain?
Correct Answer: 80
Explanation:
Let x bottles can fill the container completely.
According to the questions,
4/5 x - 3/4 x = (12 - 8)
⇒ 16x - 15x/20 = (12 - 8)
⇒ x/20 = 4
∴ x = 80
∴ Required number of bottles = 80.
