Question

If 16 men can make 320 art pieces in one day, how many men will be needed to make 960 such art pieces in one day?

• A. 48
• B. 40
• C. 28
• D. 50

Answer 1

The correct option is A 48

More men, more art pieces; less men, less art pieces. Thus, it is a case of direct proportions.
$\begin{array}{cc}Men& Artpieces\\ 16& 320\\ x& 960\end{array}$

$\Rightarrow \frac{16}{x}=\frac{320}{960}$

$\Rightarrow x=\frac{16}{320}\times 960=48$
$\therefore$ 48 men will be needed to make 960 art pieces in one day.
