Answer:

The total number of water samples to be tested are 224 .

Option (D) is correct .

Step-by-step explanation:

As given

A chemical engineer has tested 56 water samples.

These samples make up 25% of the total number of samples that need testing.

Part value = 56

Percentage = 25%

Put all the values in the formula

25 = \frac{56\times 100}{Total\ value}

25 = \frac{5600}{Total\ value}

Total\ value= \frac{5600}{25}

Total value = 224

Therefore total number of water samples to be tested are 224 .

Option (D) is correct .
