Correct Answer: B
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 \[=\frac{1344-720}{720}\times 100\] |
| \[=\frac{624}{720}\times 100=86\frac{2}{3}\]% |
