Answer 1

HERE IS UR ANSWER MATE!......

Solution:

Total price after mixing the two variety of rice is

30 \times 8.5+20 \times 9.0=255+180=R s .43530×8.5+20×9.0=255+180=Rs.435

Total amount of rice bought = 20 kg + 30 kg = 50 kg

Therefore, the Cost Price per kg is Rs. \frac{435}{50}=8.7

50

=8.7

To get a profit of 20%, the trader would sell each kg of rice at R s .\left(8.7 \times \frac{120}{100}\right)=R s .10.44Rs.(8.7×
