Answer 1

CP of total wheat = 40 × 12.50 + 30 × 14  = 500 + 420  = Rs.920 

Total Weight of Wheat = 40 kg + 30 kg  = 70 kg

note down photo solution

So, to gain 5% on wheat SP will be Rs.966  Rate for 1 kg wheat = 966/70  = Rs.13.80

Answer 2

Answer:

Rs.13.80

Step-by-step explanation:

CP = weight per kg*cost

Total Cp = 40kg*Rs12.5 + 30kg*Rs14

= Rs.920

CP=920

G%=5%

SP=?

SP=100 + G% / 100 * CP

= 100 + 5 / 100 * 920

= 105 / 100 * 920

= Rs.966

Selling price per kg = Total weight / Total SP

                                 = 40kg+30kg / 966

                                 = 70kg/966

                                 = Rs.13.80
