Answer:
Correct Answer: B
Solution:
- Number of cellular phones (both Nokia and Samsung) sold by stores, B, C and D
=(20%+15%+33%) of 6400
$ =69\times 64=4416 $
Number of Nokia cellular phones sold by stores B, C and D
=(18%+20%+30%) of 3000
= 68% of $ 3000=68\times 30=2040 $
Number of Samsung cellular phones sold by stores B, C and D
$ =4416-2040=2376 $
$ \therefore $ Required average $ =\frac{2376}{3}=792 $
