CP = 20 × 8.5 + 35 × 8.75 = 476.25
Profit = 40%
Selling Price of mixture per kg = $(\frac{{\left( {100{\rm{\;}} + {\rm{\;Profit\% }}} \right)}}{{100}} \times {\rm{CP}})$
$(= \frac{{100{\rm{\;}} + {\rm{\;}}40}}{{100}} \times 476.25 = 666.75)$
Total quantity = 20 + 35 = 55 kg
SP per kg = $(\frac{{666.75}}{{55}} \approx 12)$
∴ The Selling Price of the mixture is Rs. 12 per kgOther Questions
