sonu buys 40kg of wheat at ₹ 12.50/kg and 30kg of wheat at ₹14/ kg.At what rate per kg should he sell the mixture to gain 5 percent on the whole?

Answer 1

Cost amount of wheat-1=40*12.5= 500 rs.
Cost amount of wheat-2= 30*14= 420 rs.
Total weight of wheat=70 kg
total cost=920 rs
Profit=5*920/100 =46 rs.
Total sell price=966
Sell price of 1 kg=13.8 rs.

hope this helps!
