In 2009 a school had 1500 students. In 2010 it experienced a 12% growth in student enrolment and it experienced a further growth of 5% in 2011. Based on these figures, how many students can the school expect to enroll in 2011?
A
1680
B
1755
C
1700
D
1764
Correct Option:
D
Explanation
A 12% increase on 1500 gives 1500×1.12=1680. A further 5% increase gives 1680×1.05=1764. Successive percentage increases must be applied one after another, not simply added to the original number.
