Q. The table below provides revenues of a certain company in 2002 and 2003. By what percent did the
average quarterly revenue change from 2002 to 2003?
Quarter Quarterly revenues, MM USD
2002 2003
1st 13 17
2nd 15 18
3rd 16 17
4th 16 20

IMO Answer should be 3, am I correct?

Average of quaterly revenues for 2002

(13+15+16+16)/ 4 = 60/4 = 15

Average of quaterly revenues for 2003

(17+18+17+20)/ 4 = 72/4 = 18

percentage change from 2002 to 2003

[(18-15)/15 ] * 100 = 20 %

new average = 200% more than 2000 = 4000+2000=6000

now from 2k5-2k8 = 4*12*6000

for 2k5 = 12*2000=24000

thus, 24000( 4*3-1) = 264000.

sorry for the above post.It was for a different question.

sum for 2k5 = 60 for 2k8 = 72
change is 12

thus 12/60*100 = 20%

[(18-15)/15 ] * 100 = 20 %

why you divide by 15?
