Question

If $15$ men can pack $540$ parcels per day, how many men are needed to pack $396$ parcels per day?

Answer 1

No. of men required to pack $540$ parcels = $15$

$\therefore$ No. of men required to pack $1$ parcel = $\frac{15}{540}$

Hence, no. of men required to pack $396$ parcels = $\frac{15}{540}\times 396=11$
