82.5%
87.5%
Correct answer is D
Average sales (in thousand number) of branches B1, B3 and B6 in 2000
= 1/3 x (80 + 95 + 70) = ( 245/3 )
Average sales (in thousand number) of branches B1, B2 and B3 in 2001
= 1/3 x (105 + 65 + 110) = ( 280/3 )
Therefore Required percentage = [ (245/3)/(280/3) x 100 ] % = ( 245/280 x 100 ) % = 87.5%
