.497 is approx .5

Since we rounded up, that is, we said that slightly more marks equals a dollar, we will have to factor this back in.

1/2 mark = 1 dollar

350(1/2) = 700 dollar

+ what we rounded up, thus 704

GyanOne · Answer

0.497 marks = 1 dollar
=> 1 mark = 1/0.497 dollars
=> 350 marks = 350/0.497 = 704 dollars

Option (E)

I know this is a noob question but still I don't get this concept..
Since we rounded up 0.497 to 0.500 should we reduce the final value ? 
we got 700 so shouldn't the answer be chosen in the 600 range ?

Thanks,

Bunuel · Answer

Consider this: 0.497 marks = $1; 0.5 marks = more than $1; 0.5*700=350 marks = more than $1*700=$700. Answer: E. Similar question to practice: m14-78632.html Hope it helps.

Henry S. Hudson Jr. · Answer

To get from marks to dollars you need to multiply by slightly more than 2.

350(slightly more than 2) = slightly more than 700.
So choice E is correct.

PriyankaPalit7 · Answer

(E) 
0.497 mark = 1$.
1 mark =  \frac{1}{0.497}  $.

Let's round off 0.497 to 0.5.
1 mark =  \frac{1}{0.5}  $.
350 mark = \frac{350}{0.5}  $ = 700 $

Now we are left with option D and E.
0.5 > 0.497
We know that dividing by a bigger number gives a smaller result. Since we divided by bigger of the two numbers ( 0.5 and 0.497 ), we got a smaller result.
Dividing with 0.497 ( the smaller number), as in the original equation would have given us a result bigger than 700.
The only option bigger than 700 is  E -> 704

4d · Answer

we need not divide the complicated numbers

Using approximation

0.5 \, marks = 1 
 350 \, marks =\frac{350}{0.5} = 700

As the denominator is slightly less than 0.5 .
the quotient will be slightly more than 700 .

IMO E

BrentGMATPrepNow · Answer

Since we are comparing marks with dollars, can solve the question using  equivalent ratios

We'll use the ratio  marks / dollars

Let  x  = the number of dollars equivalent to 350 marks

We can write:  0.497 / 1  =  350 / x 
Cross multiply to get: 0.497x = 350
Solve:x = 350/0.497

Important: Do NOT use long division to evaluate 350/0.497 (the test-makers do not care about your ability to be a human calculator)

Notice that 350/0.5 = 700
Since 0.497 is a little bit less than 0.5, we can conclude that 350/0.497 is a little bit bigger than 700

Answer: E
