We can break this problem into two parts:

1) What is 1/10 percent of 5,000?

2) What is 1/10 of 5,000?

Let’s start with part 1.

To calculate 1/10 percent of 5,000 we must first remember to DIVIDE 1/10 BY 100.

So we have: (1/10)/(100)

To divide a number by 100 means to multiply it by 1/100, so we have:

1/10 x 1/100 = 1/1,000

Thus, 1/10 percent of 5,000 = 1/1,000 x 5,000 = 5.

(Note: If dividing 1/10 by 100 was confusing, consider a simpler example. Say we were asked for 20% of a number. Well, to get 20% as a fraction, we would divide 20 by 100. So 20% is 20/100, or 1/5.)

Now let's concentrate on part 2. We need to calculate 1/10 of 5,000. To do this we simply multiply 1/10 by 5,000.

1/10 x 5,000 = 500

The answer to part 1 is 5, and the answer to part 2 is 500. Their difference is 500 – 5 = 495.

Answer D.

When 1/10 percent of 5,000 is subtracted from 1/10 of 5,000, the difference is?

\frac{1}{10} * 5,000 * \frac{1}{100} = 5

\frac{1}{10} * 5,000 = 500

500 - 5 = 495

Hence, Answer is D

SOLUTION

When 1/10 percent of 5,000 is subtracted from 1/10 of 5,000, the difference is

(A) 0
(B) 50
(C) 450
(D) 495
(E) 500

1/10 of 5,000 is 500;
1/10  percent  of 5,000 is 100 times smaller than the above, so it's 5;

Thus the difference is 500-5=495.

Answer: D.

x/5000 = (1/10)/100 x/5000 = 1/1000 x=5 1/10 0f 5000 -- 500 then 500-5 =495... understood completely after getting the answer wrongly :cry:

PareshGmat · Answer

Equation to be setup is:

TimeTraveller · Answer

5,000 * 1/10* 100 = 5,000/1,000 = 5
5000 * 1/10 = 500

500 - 5 = 495. Ans - D.

BrentGMATPrepNow · Answer

We know that 10% of 5,000 = 500
So, 1% of 5,000 = 50
Which means 0.1% (aka 1/10 percent) of 5,000 =  5

1/10 of 5,000 = (1/10)(5000) = 5000/10 =  500

When we subtract   5   from   500  , we get  495

Answer: D

I think this can be done mentally without pen and paper. 
1. The first thing to look out for is the wording - there are chances you might miss out the % with 1/10 and end up getting the wrong answer. 
2. The question says 1/10% of 5000 (X) is subtracted from 1/10*5000 (Y). This just simply means that Y-X. Anytime you are confused with such wording just associate a variable and it becomes easier to understand what is happening.

For part y - 1/10 of 5000 = 500 and 
For part x - We have already calculated that 1/10 of 500 = 500. Now all we need to do is divide 500/100 to factor in the % and we get 5. 
Upon subtraction = 500-5 = 495. 
Hence, IMO D

charlie-23 · Answer

\frac{1}{(10*100)}*5000  = 5
 \frac{1}{10}*5000  = 500
500-5 =495
