Answer 2

Answer:

Price per kg he sell the mixture is 8.12

Step-by-step explanation:

Mahesh bought 50 kg. of wheat at Rs. 8 per kg.

150 kgs. at  the rate of Rs. 7 per kg

He spend for wheat

                      $50 \cdot8+150 \cdot7=400+1050\\ =1450$

He sold the mixture to get 12% profit.

Profit amount=12 % of C.P.

                     $\frac{12}{100} (1450)=174$

Selling price for (150+50=200) kg wheat=c.p. + profit

                                            $=1450+174=1624$

Selling price per kg=$\frac{1624}{200} =8.12$
