Answer 2

$\huge\tt\fbox\green{Required\:answer}$

$men \: needed \: to \: complete \: the \: work \: in \: 15 \: days \: = \: 24.$

$\therefore \: Men\:needed\:to \:completed\:the\:work\:in\:1\:day\:= \frac{24}{15}$

$therefore\:,\:Men\:needed\:to\:complete\:the\:work\:in\:40\:days\:= \frac{24}{15} \times 40 \\ = 64$

Hence, 64 men are needed to complete the work in 40days
