Question

How many liters of water does he drink in a week?

• A. 2 L
• B. 14 L
• C. 7 L
• D. 2,000 L

Answer 1

The correct option is B 14 L

Justin drinks 500 mL of water 4 times every day.

∴ In 1 day, quantity he drinks = 500 mL + 500 mL + 500 mL + 500 mL = 2,000 mL

Now, observe the conversion table:

$\text{So, 2,000 mL}=\frac{2000}{1000}\text{L = 2L}$

Number of days in a week = 7

So, quantity of water Justin will drink in a week = 2 × 7 L = 14 L of water in a week.
