Two varieties of wheat – A and B costing Rs. 9 per kg and Rs. 15 per kg were mixed in the ratio 3 : 7. If 5 kg of the mixture is sold at 25% profit, find the profit made?

One Answer on this Question

1. answer = 16.5Rs

   A=3*9=27Rs
   B=7*15=105Rs
   132 R for 10 kg
   therefore,
   1kg amount = 132/10=13.2 so,
   5kg mixture price = 13.2*5=66Rs
   mixture will sell 25%profit then the price =66*(25/10)=33/2=16.5Rs
