Company T projected the number of international students studying in the United States (US) for three consecutive school years from 2014–2015 through 2016–2017. The projected numbers for the 2014–2015 school year and during the 2016–2017 school year would be 880,000 and 1,026,080, respectively. Let X % and Y % denote the company’s predicted percentage increase in the number of international students studying in the US from school year 2014–2015 to school year 2015–2016, and from school year 2015–2016 to school year 2016–2017, respectively. Both X and Y are positive integers, and X is less than Y.
In the table, identify the value of X and the value of Y. Make only two selections, one in each column.

Official Answer :
Let A, B, and C be the projected numbers of international students for school years 2014–2015, 2015–2016, and 2016–2017, respectively.
Since A equals 880,000 and C equals 1,026,080, C divided by A equals 1,026,080 divided by 880,000 equals 1.166. So the percent increase from A to C is (C / A - 1) * 100% = 0.166 * 100% = 16.6%.
We now want to find percent increases from A to B and from B to C that yield this 16.6% increase from A to C.
To do this, first note that since C / A = (B / A) * (C / B), it follows that 1.166 = (B / A) * (C / B).
Also note that X is the percent increase from A to B, which is (B / A - 1) * 100%, and that Y is the percent increase from B to C, which is (C / B - 1) * 100%.
Finally, note that we’ve been told that X < Y.
The five answer options 2, 6, 10, 15, and 20 given in the first column, for X, stand for percentage increases of 2%, 6%, 10%, 15%, and 20% from A to B, so these answer options yield the five possible values for B / A of 1.02, 1.06, 1.1, 1.15, and 1.2, respectively.
Likewise, the same five answer options given in the second column, for Y, stand for the same five percentage increases from B to C, so they yield the same five possible values of 1.02, 1.06, 1.1, 1.15, and 1.2 for C / B.
Therefore, since 1.166 = 1.06 * 1.1, the two correct answer options must be 6 and 10.
Since we know X < Y, this gives us answers of X = 6 (corresponding to B / A = 1.06) for the first column and Y = 10 (corresponding to C / B = 1.1) for the second column.
X: The correct answer is 6.
Y: The correct answer is 10.
Let A, B, and C be the projected numbers of international students for school years 2014–2015, 2015–2016, and 2016–2017, respectively.
Since A equals 880,000 and C equals 1,026,080, C divided by A equals 1,026,080 divided by 880,000 equals 1.166. So the percent increase from A to C is (C / A - 1) * 100% = 0.166 * 100% = 16.6%.
We now want to find percent increases from A to B and from B to C that yield this 16.6% increase from A to C.

The projected numbers for the 2014–2015 school year and during the 2016–2017 school year would be 880,000 and 1,026,080, respectively. Let X % and Y % denote the company’s predicted percentage increase in the number of international students studying in the US from school year 2014–2015 to school year 2015–2016, and from school year 2015–2016 to school year 2016–2017, respectively. Both X and Y are positive integers, and X is less than Y.
In the table, identify the value of X and the value of Y. Make only two selections, one in each column.
We can see the following:
880,000( 1 + X/100)(1 + Y/100) = 1,026,080
This is one of the few times I'd use the calculator to answer a question to divide 1,026,080 by 880,000 to get 1.166.
So, ( 1 + X/100)(1 + Y/100) = 1.166.
Scanning the answer choices, we can quickly eliminate 20 since 1.2 is already greater than 1.166.
Then, we can note that the only way to get a number that ends in 6 by using the answer choices is to use 6.
And the only numbers we can multiply by 6 to get a decimal that ends in 6 are 6 and 10.
1.06 × 1.06 does not equal 1.166.
1.06 × 1.10 = 1.166
X is less than Y, so the X = 6 and Y = 10
Correct answer: 6, 10
