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?
Answer: Option B
:
B
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 [11252−93729372]×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 [9137−73527352]×100%=24%
