Solution



Given:
    • A teacher took a container filled with 16 liters of water to a school picnic
    • After several students had taken water from the container, the container had 14 liters of water left

To find:
    • The percent decrease in the amount of water in the container

Approach and Working:
Initially the water amount was 16 liters and finally it became 14 liters
    • Decrease in the amount of water = (16 – 14) liters = 2 liters
    • Therefore, percent decrease = \(\frac{2}{16} * 100\) = 12.5%

Hence, the correct answer is option C.

Answer: C
