A. 12 B. 13 C. 14 D. 15 E. 16 You can use ratios to solve it too. Kelly received 1/3 more votes than Mike which means that if Mike got 3 votes, Kelly got 4 votes (1/3 more than Mike). Since votes cannot be fractional, Mike must have got at least 3 votes and Kelly must have got at least 4 votes. They must have got at least 7 votes together. Actual number of votes could be any multiple of 7. The only multiple of 7 in the options is 14. For more on ratios, check: http://www.veritasprep.com/blog/2011/03 ... ofratios/

K = M + 1/3M K = (4/3)M M+K=M+(4/3)M=Total Total = (7/3)M M=(3/7)Total Total must be a multiple of 7 because Mary can't receive fractional numbers of votes. Only option that is a multiple of 7 is 14. Ans: "C"

K = (4/3)M
=> M+K = (7/3)*M
=> M = (3/7)*(M+K)
M+K has to be a multiple of 7.
Only possible option here is 14.
Answer is C.

7/3 * M = total votes
means total votes/7 = integer.
14 fits

It's not clear to whether 1/3 has to be applied to the votes cast to Mike or to the total votes Please help

So for every 3 votes, Kelly received 1 extra vote i.e. she received 4 votes.

K = 4/3 M we know M has to be a multiple of 3 in order to get an integer for K + M
plug in a couple values for M:
M = 3 => K = 3 + 1 = 4 M + K = 7 (not in choices)
M = 6 => K = 6 + 2 = 8 M + K = 14 (answer C)

Let votes to Mike = x Then votes to Kelly \(= x + \frac{x}{3}\) Total votes \(= 2x + \frac{x}{3} = \frac{7x}{3}\) \(x = (Total Votes) * \frac{3}{7}\) Total votes should be divisible by 7, only 14 fits in Answer = C

A. 12 B. 13 C. 14 D. 15 E. 16 If we let k = the number of votes Mike received, then (4/3)k = the number of votes Kelly received. Thus, they received a total of k + 4k/3 = 3k/3 + 4k/3 = 7k/3 votes. Since 7k/3 has to be an integer, k can be any multiple of 3. When k is 3, the total number of votes is 7(3)/3 = 7. When k is 6, the total number of votes is 7(6)/3 = 14. Answer: C

Let the number of votes for Mike and Kelly be M and K respectively. As per the statement K=(4/3)*M. K/M=4/3. The sum has to be a multiple of 7. The total number of votes need to be a multiple of 7. Only 14 or option C fits the bill. Option C it is !!

A. 12 B. 13 C. 14 D. 15 E. 16 Let the vote received by Mike be M. Vote Received by Kelly is 1/3 more than the votes of Mike = (1/3)M +M = (4/3)M Ratio of votes of Kelly to Mike = 4/3 Since votes should be a natural number. So it must be a multiple of 4+3 = 7. Only Option C i.e. 14 is a multiple of 7. Answer C

A. 12 B. 13 C. 14 D. 15 E. 16
let mike got x votes, then Kelly got (x+1/3x) votes
thus total votes=x+(x+1/3x)=(7/3)x.
so x=(3*total votes)/7. since the votes have to be integer then we have to pick a nunber which is divisible by 7 to make x as an integer.
only option c is divisivle by 7 and thus x=6 and Kelly got 8 votes.=14
C is correct.
