1. A tank is 30% full with water. If 18 liters of water is added the tank become 3/4 full. What is the capacity of the tank?
- A. 36
- B. 36
- C. 36
- D. 36
Answer: Option B
Explanation:
3/4 ≡ 3/4 x 100% = 75%
Change in = 75% - 30% = 45%
Now, 45% capacity = 18 liter
So, 100% capacity = 18 x 100 / 45 = 40 liter
