• A. $5$
• B. $10$
• C. $12$
• D. $15$

Answer 1

The correct option is B $10$

If $6$ painters complete drawings in $5$ hours, then $x$ painters can complete drawings in $3$ hours.0

Therefore, $6\times 5=k=x\times 3$

$\Rightarrow x=\frac{6\times 5}{3}=10$

Therefore, numbers of painters are $10$.
