B) 85%
C) 118%
D) Cannot be determined
E) None of these
Correct Answer: A
Solution :
Let the population of State A in 1999 be x. \[\therefore \] Population in 2000 \[=x\times \frac{140}{100}\] Population in 2001 \[=\frac{x\times 140\times 145}{100\times 100}=\frac{203x}{100}\] \[=x\left( 1+\frac{103}{100} \right)\] Clearly, effective percentage increase = 103%You need to login to perform this action.
