Solution:

  • Number of cellular phones (both Nokia and Samsung) sold by store B = 21% of $ 6400=21\times 64=1344 $ Number of Nokia cellular phones sold by store A = 24% of $ 3000=24\times 30=720 $

$ \therefore $ Required percentage $ =\frac{1344-720}{720}\times 100 $ $ =\frac{624}{720}\times 100=86\frac{2}{3} $ %
