Question

If $5$ workers can build a fence in $65$ days, how long would it take $13$ workers to build the same fence?

• A. $15$ days
• B. $20$ days
• C. $25$ days
• D. $35$ days

Answer 1

Answer: (C)

$25$ days

More the workers, lesser will be the time it will take to build the fence.

Let $x$ be the number of days required to build the fence.
In the equation form, we get
$5\times 65=13\times x$
$\therefore x=\frac{5\times 65}{13}$
$=5\times 5=25$
