A jar is filled with 3/5 of a solution. When 3.2 liters of solution are added, it becomes 7/8 full. What is the total capacity of the jar?
Show answer & explanation
Correct answer: C
Explanation
Given:
Initial fraction = 3/5
Final fraction = 7/8
Solution added = 3.2 liters
Difference = 7/8 − 3/5 = (35 − 24)/40 = 11/40
Total capacity × 11/40 = 3.2
Total capacity = 3.2 × 40 / 11 = 11.64 liters
