Question

A grocer purchased 80 kg of rice at Rs 90 per kg and sold at Rs 99 per kg. Find his profit

Answer 1

So we know that we bought 80kg of rice at 90 Rs each.

So he spent 90*80 = 7200 Rs on his rice.

He then sold that much rice at 99 Rs/Kg

So he made 99*80 = 7920 Rs

To find his profit, just subtract the 2 values.

7920-7200 = 720

Therfore, his profit was 720 Rs
