Question

A box contains $50$ packets of biscuits each weighting $120$g. How many such boxes can be loaded in a van which cannot carry beyond $900$kg ?

Answer 1

weight of $1$ packet $=120gm$

weight of $50$ packets $=120\times 50$ gm = $6$ kg

$6$ kg is weight of $1$ box

$900$ kg is weight of $\frac{1}{6}\ast 900$

$=150$ boxes
