Since there are 4 accounts in which all Karina' investments are divided &
we need a minimum percentage of the account with the largest balance,
the other 3 accounts must have the highest balance.

Let x be the minimum percentage of the account with the largest balance
\(x - 3 + x - 2 + x - 1 + x > 100\) -> \(4x - 6 > 100\) -> \(4x > 104\) -> \(x > 26\)

Therefore, Option C(27) is the minimum percent of Karina's money in the largest account.

If we're not sure where to start, we'll look to the answers.
This is an Alternative approach.

Since we're looking for the minimum, we'll start with the smallest possible answer: 25.
If the minimum (in the largest account) was 25, then since none of the accounts have the same value, they must have less than 25 each. At most, they'll be 24, 23 and 22. But then their sum is 25 + 24 + 23 +22 which is less than 100. Impossible!
Similarly, if (B) were correct then the sum of the percentages would be at most 26 + 25 + 24 + 23 = 98 < 100. Also impossible.
(C) works out: 27 + 26 + 25 + 22 = 100 meaning that we can divide all the money between the 4 accounts.

(C) is our answer.

Let's say Karina's entire portfolio is worth $100 altogether.
So, we want to divide this $100 into four integer amounts: w, x, y, z, where w < x < y < z, and we want to minimize the value of z
In order to MINIMIZE the value of the z, we must MAXIMIZE the values of w, x, and y.

Now let's test the answer choices

A. 25
In other words, z = 25
So, we have: w < x < y < 25 and all 4 values must add to 100
So, the greatest possible value of y is 24, the greatest possible value of x is 23, and the greatest possible value of w is 22
25 + 24 + 23 + 22 = 94.
No good. We want the 4 values to add to 100. ELIMINATE A

B. 26
In other words, z = 26
So, we have: w < x < y < 26 and all 4 values must add to 100
So, the greatest possible values of w, x and y are 23, 24, and 25 respectively.
26 + 25 + 24 + 23 = 98.
Unfortunately the 4 values do NOT add to 100, so we can ELIMINATE B

C. 27
In other words, z = 27
So, the greatest possible values of w, x and y are 24, 25, and 26 respectively.
27 + 26 + 25 + 24 = 102.
In this case the sum is greater than 100, but that's okay. We can just make one of the values smaller.
For example, the 4 values add to 100 when w, x, y and z equal 22, 25, 26, and 27 respectively

Answer: C

we can try like

25, 25, 25, 25 equal division
23, 24,26,27 min largest division.

adding and substracting 1 from the middle value.
adding and substracting 2 from extreme values.

Hey Simmones
(E) can work, but we are asked what is the minimum amount - therefore, for (E) to be the answer, all the other answers (A)-(D) must not work. but since (C) does work, it is the answer, and (E) isn't.
Hope this helps!

Since we want to minimize the percent of Katrina’s money in the account with the largest balance, we need to maximize the percents of the 3 accounts with the smallest balances. If we let one of these 3 accounts have 100/4 = 25 percent of her money, then the 3 accounts with the smallest balances could be 23, 24 and 25 percent. Combined, they make up

23 + 24 + 25 = 72 percent of the total balance.

So, the fourth account would have 28 percent of her money.

The accounts would have these percentages: 23, 24, 25, and 28.

However, we notice that 28 is not the smallest possible percent value, since we can decrease 28 by 1 and increase 25 by 1 to obtain 23, 24, 26 and 27 percent. Now, 27 is the minimum percentage for the largest account, since further decreasing 27 would result in multiple accounts with the same percent figure.

Hi All,

We're told that all assets in Karina's investment portfolio are divided between an IRA, 401k, and two separate taxable accounts and that NO two accounts have the SAME amount of money and all four have at least SOME money in them. If each account has a whole-number percent of Karina's money, we're asked for the MINIMUM percent of Karina's money that could be in the account with the LARGEST balance. This question can be solved in a number of different ways, including by TESTing THE ANSWERS.

While this prompt is wordy, it can be simplified to the following: since 100% of the money has to be spread across 4 accounts with DIFFERENT integer-percent totals, we need to find 4 DIFFERENT numbers that add up to 100. We're then asked to find the SMALLEST possible integer value for the LARGEST of the 4 numbers.

Let's TEST Answer A: 25
IF... largest = 25, then the next 3 could be as large as....24, 23 and 22
25+24+23+22 = 94
This is NOT large enough; the 4 numbers need to total 100. Eliminate Answer A

Answer B: 26
IF... largest = 26, then the next 3 could be as large as....25, 24 and 23
26+25+24+23 = 98
This is NOT large enough; the 4 numbers need to total 100. Eliminate Answer B

Answer C: 27
IF... largest = 27, then the next 3 could be as large as....26, 25 and 24
27+26+25+24 = 102
This is clearly too large, BUT we could reduce the smallest value....
The group could then be 27, 26, 25 and 22.... which would total 100.
Thus, the smallest possible value for the LARGEST percent is 27.

Final Answer:

C

does this not mean minimum percent among all the percent

All assets in Karina's investment portfolio are divided between an IRA, 401k, and two separate taxable accounts. No two accounts have the same amount of money and all four have at least some money in them. If each account has a whole-number percent of Karina's money, what is the minimum percent of Karina's money that could be in the account with the largest balance?

A. 25
B. 26
C. 27
D. 28
E. 29

Let's say Karina's entire portfolio is worth $100 altogether.
So, we want to divide this $100 into four integer amounts: w, x, y, z, where w < x < y < z, and we want to minimize the value of z
In order to MINIMIZE the value of the z, we must MAXIMIZE the values of w, x, and y.

Now let's test the answer choices

A. 25
In other words, z = 25
So, we have: w < x < y < 25 and all 4 values must add to 100
So, the greatest possible value of y is 24, the greatest possible value of x is 23, and the greatest possible value of w is 22
25 + 24 + 23 + 22 = 94.
No good. We want the 4 values to add to 100. ELIMINATE A

B. 26
In other words, z = 26
So, we have: w < x < y < 26 and all 4 values must add to 100
So, the greatest possible values of w, x and y are 23, 24, and 25 respectively.
26 + 25 + 24 + 23 = 98.
Unfortunately the 4 values do NOT add to 100, so we can ELIMINATE B

C. 27
In other words, z = 27
So, the greatest possible values of w, x and y are 24, 25, and 26 respectively.
27 + 26 + 25 + 24 = 102.
In this case the sum is greater than 100, but that's okay. We can just make one of the values smaller.
For example, the 4 values add to 100 when w, x, y and z equal 22, 25, 26, and 27 respectively

Answer: C

Brent

If each account has a whole-number percent of Karina's money, what is the minimum percent of Karina's money that could be in the account with the largest balance?

Let the minimum percent of Karina's money that could be in the account with the largest balance = x%

To minimize percent of Karina's money that could be in the account with the largest balance, we have to maximize percent of Karina's money that could be in other accounts

x + (x-1) + (x-2) + (x-3) > 100%
4x - 6 > 100
x > 26.5%

Since x is whole-number
x = 27%

IMO C
