Question

35 men can do a piece of work in 20 days. how much days will 25 men take to finish the same work? solve this question using direct and inverse propotion

Answer 1

$Here,\ no.\ of\ workers\ and\ time\ for\ the\ work\ are\ inversely \\ proportional. \\ \\ 20\ \alpha\ \frac{1}{35}\\ \\ Let\ constant\ of\ proportionality\ be\ k. \\ \\ 20 = \frac{k}{35} \\ \\ k = 20 \times 35 = 700$

$\\ \\ Let\ the\ time\ for\ work\ with\ 25\ men\ be\ x. \\ \\ x\ \alpha\ \frac{1}{25} \\ \\ x = \frac{k}{25} = \frac{700}{25} = \bold{28} \\ \\ \\ \therefore\ 25\ men\ will\ take\ \bold{28\ days}\ to\ complete\ the\ same\ work.$
