Kudos for a correct solution.


Solution:

Let m = number of males, and let f = number of females. Let number of males who voted for brand Y be y.

Statement I:

Males Females Sum
X 0.4f
Y y
Sum m f 1600

From above table, it is not possible to find y. Hence not sufficient.

Statement II:

Males Females Sum
X 0.65m
Y y
Sum m f 1600

From above table, it follows that: 0.65m + y = m. --> y = 0.35m. --> 35% of males voted for brand Y. Hence, sufficient.

Answer: B

Statement (1) : Doesn't state anything about % of Male votes.
Not Suffuicient.

Statement (2): 65% of males voted for brand X hence rest of 35% of males voted for Y.

Sufficient.

Ans - B

Kudos for a correct solution.


VERITAS PREP OFFICIAL SOLUTION:

Question Type: What Is the Value? What percent of males in a certain poll voted for coffee Y?

Given information from the question stem: A total of 1,600 people voted. Each voted for X or Y. No one voted for both. And because you’re dealing with people/votes, the numbers for X and Y must be integers.

Statement 1: 40% of females voted for brand X. This statement is not sufficient to tell you what percent of males voted for brand X. Not sufficient. The answer
will either be B, C, or E.

Statement 2: 65% of the males voted for X. This statement might appear to be insufficient as it does not even talk about brand Y. However, since you know that there are only two brands, X and Y, the percent of males who chose X + he percent who chose Y must equal 100%. So if 65% chose X, the other 35% voted for Y. And since the question asks for the percent, not the actual number of males, 35% is sufficient.

The correct answer is B.

Mx = Males who voted for X
My = Males who voted for Y
Fx = Females who voted for X
Fy = Females who voted for Y

Mx + My + Fx + Fy = 1600

TO find: Percent of Males who voted for Y

(1) Forty percent of the females polled voted for brand X.

that implies, 60% voted for Y. But what percent of 1600 are women. And what percent of men voted for the either?
No such info. Hence, Insufficient

(2) Sixty-five percent of the males voted for brand X.

So, 35 percent voted for Y. Enough to give the naswer "What percentage" of males voted for Y

Hence, B.

Is voting for X and Y mutually exclusive?

From : 40% of females voted for brand X., Can I not infer: 60% of females voted for brand Y and hence know % of males who voted for brand Y?
