reciprocal of 0.004 = Recip(4/1000)
= 1000/4
= 250

1/5th of 250 = 50

C. 500
D. 5,000
E. 50,000


As the calculation we're asked to do is relatively straightforward, we'll just do it.
This is a Precise approach.

1/5 * 1/0.004 = 1/(5*0.004) = 1/0.02 = 50/1 = 50

(B) is our answer.

Solution



To find:
    • The value of \(\frac{1}{5}\) of the reciprocal of 0.004 percent

Approach and Working:
    • The value of 0.004 percent = \(\frac{4}{1000}*\frac{1}{100}\)
    • Reciprocal of the value of 0.004 percent = \(\frac{100000}{4}\) = 25000
    • \(\frac{1}{5}\) of the value of the reciprocal of the value of 0.004 percent = \(25000 * \frac{1}{5} = 5000\)

Hence, the correct answer is option D.

Answer: D

Did I miss something?

0.004=4/1000 but 0.004%=4/1000/100

Therefore I came up to answer D
Can someone explain Where I went wrong? I

Hey LevanKhukhunashvili,
Your approach is correct.
(4/1000)/100 = \(\frac{4}{100000}\)

Hence, reciprocal = \(\frac{100000}{4}\) = 25000

\(\frac{1}{5}\) of the reciprocal value = \(\frac{1}{5}\) * 25000 = 5000

A. 0.5
B. 50
C. 500
D. 5,000
E. 50,000



Note: 0.004 percent

Given,

0.004 %
=0.004 / 100
= 0.00004

0.00004 = 4 / 100000

Reciprocal of 4 / 100000

= 100000 / 4
=25000

1/5 of 25000
=5000

Thus the best answer is D.

Thank you!
Another question, if i may; So as more people get the correct answer, the difficulty level goes down? And is time taken also factored into the difficulty level?

1/5 of the reciprocal of 0.004 percent is:

1/5 x 1/(0.004/100) = 1/5 x 100/0.004 = 100/0.02 = 100/(2/100) = 10,000/2 = 5,000

Answer: D

Bunuel

as the percent of correct attempts increases or decreases decides the difficulty, at what point should one measure the true difficulty of the question? or is it based on one's individual ability?

The difficulty tag shows the level of the question now. If after some time due to the attempts the difficulty changes the tag will change accordingly.

First lets find the reciprocal of 0.004:

1/(0.004/100) = 1/(4/100,000) = 100,000/4

Now lets multiply by 1/5:

1/5 * 100,000/4 = 20,000 / 4 = 5,000

Option D
