Let be x total number of screws the worker needs to examine in order to reject 300 screws. x*0.03%=300 ---> 0.0003x=300 --->  \frac{3x}{10000}  =300 ---> x=1,000,000  D)

ScottTargetTestPrep · Answer

Solution:
 
We can let n be the number of screws the worker examines and create the equation:

0.03/100 * n = 300

n = 300 * 100/0.03 = 10,000 * 100 = 1,000,000

Answer: D

Deconstructing the Question

An industrial worker rejects   0.03\%   of screws as defective.

We are told that he rejected

300

screws.

We need to find the total number of screws examined.

Step-by-step

Convert the percentage to decimal form.

0.03\%=\frac{0.03}{100}=0.0003

Let the total number of screws be

N

Then

0.0003N=300

Solve

N=\frac{300}{0.0003}

Multiply numerator and denominator by  10000

N=\frac{300	imes10000}{3}

N=1000000

Answer D
