Question

$36$ men can construct a bridge in $18$ days. In how many days will $27$ men complete the construction?

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

Answer 1

The correct option is D $24$

Given :

36 men can construct a bridge in 18 days

Less men given for the construction , hence more days will be taken

1 man completes the construction in $36\times 18$ days

27 men completes the construction in

$36\times 18÷27$ days

$\Rightarrow 24$ days

Hence 27 men will take 24 days to complete the construction .
