Question

If $6$ painters can complete $9$ drawing in $5$ hours then

How many painters will make $18$ drawing in $5$ hours?

• A. $11$
• B. $12$
• C. $13$
• D. $14$

Answer 1

The correct option is B $12$

Let number of painters required for painting 18 drawing is $x$

Now since no. of painters is directly proportion to no. of drawing
$\frac{6}{9}=\frac{x}{18}\Rightarrow x=\frac{6\times 18}{9}=12$
