(A) 5% increase

(B) 2% increase

(C) 1% decrease

(D) 3% decrease

(E) 6% decrease


Let Easter eggs (E) and Easter bunnies (B) be 100 each
Then, ratio of Easter eggs to Easter bunnies = 1

Easter eggs (E) in 2010 = 100(1.20)(0.83)=99.6

EB in 2010 = (0.80)(1.22)=0.976

B=E0.976=99.60.976=102.04

Therefore, % change = 2.04 increase
Hence, option B
