Question

What is the percentage change in the percentage increase in the number of non-local North Indian people in City A and non-local Foreign Nationals of the Asian category in City D, from 2001 to 2002?

• A. 11%
• B. 20%
• C. 16%
• D. 31%

Answer 1

The correct option is B

20%

It seems that the calculation is intensive, but you should realize that most of the numbers cancel out
number of non-local North Indian people in City A in 2001= 17% of 26.2% of 9372
number of non-local North Indian people in City A in 2002= 17% of 26.2% of 11252
hence, percentage change is $\left[\frac{11252-9372}{9372}\right]\times 100\%=20\%$
Non-local Foreign Nationals of the Asian category in City D in 2001= 46% of 18.8% of 7352
Non-local Foreign Nationals of the Asian category in City D in 2002= 46% of 18.8% of 9137


hence, percentage change is $\left[\frac{9137-7352}{7352}\right]\times 100\%=24\%$

% change in % increase $=\frac{4}{20}\times 100=20\%$
