Question

What is the average of the number Pen drives, CDs and Computers produced by Company B?

• A. 840
• B. 280
• C. 270
• D. 300
• E. None of these

Answer 1

The correct option is B 280

Company A,
Total products $\Rightarrow 800$
$CDs\Rightarrow 800\times \frac{20}{100}=160$
$Computers\Rightarrow 340-240=100$
$Pendrives\Rightarrow 270$
$Phones\Rightarrow 270$
Company B,
Total Products $\Rightarrow 1000$
$Pendrives=1000\times 20\%=1000\times \frac{20}{100}=20$
$CDs=400$
$Phones\Rightarrow (1000-400-200)\times \frac{2}{5}=160$
$Computers\Rightarrow 240$
Required average $=\frac{270+400+240}{3}=280$
