Question { L&T, 26830 }

If he sells 40 mangoes, he will get the selling price of 4
mangoes extra, What is his percentage increase in profit ?

Answer

Actually, question itself is wrong. In question its not
given that how much profit he was gaining earlier which
means if we consider Rs.1 as selling price then his/her
total selling price is Rs.40, but as he's earning 4 extra
Rps. for selling 40 mangoes,so now its Rs.44. But we don't
know his earlier profit, so can we calculate increase in
profit. Because earlier profit may be 20 Rps. or 30 Rps. or
whatever. So increase of 4 Rps. will have different increase
in percent of profit.
