1. One-third of a cylindrical oil tank is filled. If 3 more liters are added, a half of the tank will be filled. What is the capacity, in liters, of the tank?
- A. 15
- B. 15
- C. 15
- D. 15
Answer: Option D
Explanation:
Change in capacity = 1/2 - 1/3 = 1/6
Now, 1/6 of the capacity = 3 liter
So, actual capacity = 3×6 = 18 liter
