Question

$36$ men can complete a piece of work in $18$ days. In how many days will $27$ men complete the same work?

• A. $12$
• B. $18$
• C. $22$
• D. $24$

Answer 1

The correct option is D $24$

Let the required number of days be x. Then, less men, more days.
$\therefore$ 27 : 36 :: 18 : x
$\Rightarrow 27\times x=36\times 18$
$\Rightarrow x=\frac{36\times 18}{27}\Rightarrow x=24$
