The table above shows 5 countries and their populations in 2001 and 2025. Which country has the highest population growth rate?

Is there a shortcut that avoids long division? I know how to do it (pop2025-pop2001/pop2001), but it takes me longer than 2 minutes.

Sorry, I'm not sure how to make a table. I tried to space it out to make it easier to read but when I submit it removes the spaces.

No, not sure at all. It seems straight forward enough, I'm just wondering if I'm missing a shortcut.

Spoiler: :: Here is the solution from Veritas (not very helpful):
(B) Calculate the growth rate of each country:

Growth Rate = $$\frac{Pop2025-Pop2001}{Pop2001}$$

(A) $$\frac{1,431-1,273}{1,273} = .12$$
(B) $$\frac{1.363-1,033}{1,033}= .32$$
(C) $$\frac{346-285}{285}= .21$$
(D) $$\frac{252-206}{206}= .22$$
(E) $$\frac{209-172}{172}= .22$$

Is there any quick way to get down to answer?

This seems to be more math based !!!
This will take up time...

I tried to answer by just looking out range but went wrong!

Q. Which country has the highest population growth rate?

Growth Rate = $$\frac{Pop2025-Pop2001}{Pop2001}$$

(A) $$\frac{1,431-1,273}{1,273} = \frac{158}{1273}$$
(B) $$\frac{1.363-1,033}{1,033}= \frac{330}{1033}$$
(C) $$\frac{346-285}{285}= \frac{61}{285}$$
(D) $$\frac{252-206}{206}= \frac{46}{206}$$
(E) $$\frac{209-172}{172}= \frac{37}{172}$$

If you take A and B, numerator increased and denominator decreased in A compared to A.
Thus rule out A and Keep B aside.

C. 61 is between 4-5 times 285......i.e., its fraction is 1/4-1/5
D. 46 is between 4-5 times 206......i.e., its fraction is 1/4-1/5
E. 37(approx 40) is between 4-5 times 206......i.e., its fraction is 1/4-1/5

coming to B, 330 is nearly 3 times its denominator making fraction 1/3 which is definitely greater than 1/4-1/5(ruling out C, D and E).
