उत्तर

Let the required weight of the parcel be x grams.

Number of parcels 8 40
Weight of the parcels in grams 500 x

As the number of parcels increases weight of a parcel decreases.

∴ They are in inverse proportion.

x1y1 = x2y2

8 × 500 = 40 × x

x = `(8 xx 500)/40`

x = 100

Weight of each parcel = 100 grams
