Question

$3$ men or $5$ women can do a work in $12$ days. How long will $6$ men and $5$ women take to finish the work

• A. $6days$
• B. $5days$
• C. $4days$
• D. $3days$

Answer 1

Answer: (C)

$4days$

$3men\equiv 5women$

$1man=\frac{5}{3}\times 6=10women$

$(6men+5women)\equiv 15women$

$5$ women can do the work in $12$ days.

$1$ woman can do it in $12\times 5$ days.

Therefore, $15$ women can do it in $\frac{12\times 5}{15}=4$ days
