Question

an inspector rejects 0.08% of the meters as defective. how many will he examine to reject 2?

Answer 1

Answer:

2500 m

Step-by-step explanation:

0.08 % rejected

0.08 is  rejected out of 100

1 is rejected out of  = 100/(0.08) = 10000/8 = 1250

2 is rejected out of  = 2*1250 = 2500

Answer 2

Answer:

2500 meters

Step-by-step explanation:

Let us suppose the inspector examines x meters.

Now, it has been given that he rejects 0.08% of the meters as defective.

So, in order to reject 2 meters, we have the below equation

$\frac{0.08x}{100}=2$

Now, eliminating the decimal, we get

$\frac{8x}{10000}=2$

Cross multiplying, we get

$8x=20000$

Divide both sides by 8

$x=\frac{20000}{8}\\\\x=2500$

Therefore, he examines 2500 meters to reject 2 meters.
