Answer 2

A woman bought 130kg of tomatoes for 52.00.she sold half of them at a profit of 30%.The rest of the tomatoes began to go bad,she then reduced the selling price per kg by 12%.calculate the new selling price per kg?

The woman paid $52 for 130 kg, or $26 for 65 kg.  (40c/kg buying price)

She sold half of them, 65 kg, for a profit of 30%.

30% of $26 is $7.80.

So she sold the 1st 65 kg for $26 + $7.80 = $33.80.   (52c/kg selling price)

The selling price for the reminaing 65kg took a reduction of 12%.

12% of $33.80 = $4.056.

So, the final 65 kg were sold for $33.80 - $4.056 = $29.744.

The final selling price is $29.744 per 65 kg = $0.4576/kg   (45.76c/kg final selling price)
