Question

A seller uses 840 gm in place of 1 kg to sell his goods. Find his actual profit/loss % When he sells his article on 4% loss on cost price ?

Answer 1

Let 1 kg of Rs 100 then 840 gm is Of Rs. 84

Now (label on can 1 kg but contains 840 kg) so for customer it is of Rs 100 and further gives 4% discount (he sells his article on 4% loss on cost price)

So now S.P = Rs. 96

But actually it contains 840 gm so C.P for shopkeeper = Rs 84

$\therefore S.P=Rs96$ $C.P=RS84$

profit = $\frac{S.P-C.P}{C.P}\times 100$

$=\frac{96-84}{84}\times 100=14.285$% (approx) profit
