STEP 1= CP Of FirsT Variety Of Wheat = 40*6.25 = Rs 250
CP Of Second Variety Of Wheat = 30*7 = Rs 210
Total CP = 250+210 = Rs 460 For 40+30 = 70 kg
To Gain 5% = 460+5/100*460 = Rs 483 For 70 kg
Rate At 1 kg = 483/70 = Rs 6.9 per kg
STEP 2 = cost price of 1st wheat brought = 40 x 6.25 =Rs 250
cost price of 2nd wheat brought =30 x 7 = Rs 210
total cost price =250+210 =Rs 460
where,40kg+30kg=70 kg
profit on whole is 5% = 460+5/100 x 460 = Rs 483 for 70 kg
cost per kg is = 480/70 =Rs 6.9 per kg
