Correct Answer: 792
Solution :
Total number =11200
Total number of laptops sold by A = 18% of 11200 = $\frac{18}{100}\times 11200$ = 2016
⇒ Dell laptops sold by store A = $\frac{5}{5+4}\times 2016$ = 1120
Total number of laptops sold by C = 20% of 11200 = $\frac{20}{100}\times 11200$ = 2240
⇒ Dell laptops sold by store C = $\frac{1}{1+4}\times 2240$ = 448
Total number of laptops sold by D = 12% of 11200 = $\frac{12}{100}\times 11200$ = 1344
⇒ Dell laptops sold by store D = $\frac{11}{11+10}\times 1344$ = 704
Total number of laptops sold by E = 14% of 11200 = $\frac{14}{100}\times 11200$ = 1568
⇒ Dell laptops sold by store E = $\frac{4}{4+3}\times 1568$ = 896
⇒ Average = $\frac{1120+448+704+896}{4}=\frac{3168}{4} $= 792
Hence, the correct answer is 792.
