Divide the vote into 10 parts. He got 4 parts, he needs 5 parts. So he need 1 part out of the remaining 6 parts or .166666666...%  plus one vote.

But how did you get six remaining parts, partner?

The other candidate received the six remaining "parts" (or sixtenths of the vote).
For the vote to have been 50/50, one of the other candidates "tenths" would have to convert to Mr. Kramer. So one tenth out of six tenths is 1/6 = .1666667. That is the fraction of the TOTAL vote that would have to be shifted in order for Mr. Kramer to have tied the vote 50/50.

1/6 = .1666667 is a half of your success.
but the stem asks about approximate percentage!
The correct answer is 17%

Great point Stolyar!! Hopefully we would recognize this in the choices (and also remember to round up rather than down), but in other questions such as CR, if we omit something small like "EXCEPT", we will be cooked!
AkamaiBrah, reading what you wrote two posts above made me laugh out loud at work!!! Curly, can you repeat that question/statement please?

Strictily speaking, since 1/6 has infinitely repeating decimals, an approximate could be:
17%
16.7%
16.67%
etc.
Just have to look at the answers and pick appropriate choice.

Assume there are 100 votes
Kramer has 40 and the winner has 60
Kramer needs atleast 50 which means atleast 10 out of 60 which is 16.67%
Hence I'll go with D

Answer A
Time 1:43

i.e. 942568 = 940000

D, of course.
10%/60% = 16.66% ~~ 17%.

Is it D 17%
Assume the total votes cast 100 votes recd 40, remaining votes 60. K needs 10 more votes to get 50% . hence percent out of remaining = 100*10/60 = 17%

Votes he has is 942568 = 0.4 S where S is total of all votes
He need 0.5 S votes.
So % of Votes Required = 0.5S  0.4 S
  = 0.1 S/ 0.6 S = 17%.
Votes Remaining S  0.4S

Note to self. Big numbers mean its universally applicable. so pick easy numbers like 100 and go ahead with the problem and would end up with the same result.

I will aproximate to
D. 15%
let total vote cast is x
0.4 x = 942,568
or
x = 23564200
if he had to get 50% he need another 10%
0.1 x = 2356420
remaining votes:
0.6 x = 14138520
2356420 / 14138520

Let me try a simpler one.
Lets assume that candidate got 40% votes and total votes is 100.
Candidate won = 40
Remaining = 60
To get 50%, candidate requires 10 votes from 100 which is 10% and 10 votes from 60.
10/60 = 1/6 = .166 = 16.67%
Which is approx 17%. Hence the answer is D.
Whatz OA?

Right. Its D.
Good explanation. It doesnt matter what are the actual numbers as we are dealing with %ge only.

Kramer received 40% of the votes, so 60% = (60/40)(942568) = (3/2)(942568)
Replace 942568 with T.
He needs 50% so (5/4)(T)
Difference = 3/2T  5/4T = 1/4T
% = (1/4T)/(3/2T) *100% = 16.66% ~ 17% (D)

Kramer ( Cosmo ? ) has 40 %. He needs 5040 = 10 % of the remaining ( 60%) votes to win at least 50 % of all the votes cast.
Thus, the percentage of the remaining votes = (10/60)*100 = 16.66 %.

A)10% B)12% C) 15% D) 17% E)20%
Answer is D, but somehow i'm not using the write numbers or I'm rounding wrong or something cause I can't get it. Thanks for the help!
