Answer 1

SOLUTION

The standard quantity of water is 2000 liters

The quantity of water in the pool is 10,000

Since 3 chlorine is added to every 2000 liters of water then the number of chlorine added to 10000 liters of water is:

$\begin{gathered} \frac{10000}{2000}\times3 \\ =5\times3 \\ =15 \end{gathered}$

Since 8 tablets is added instead of 15 then:

The park pool has less chlorine than the safety standards require
