Answer:

Correct Answer: C

Solution:

  • Cost price of 30 kg of wheat $ =30\times 45=Rs.1350 $ Total SP for an overall profit of 25% $ =\frac{1350\times 125}{100}=Rs.,1687.5 $ SP of 12% of 30 kg wheat = SP of 12 kg wheat $ =12\times 50=Rs.,600 $ Expected SP of 18 kg of remaining wheat $ =1687.5-600=Rs.1087.5 $ Required selling price per kg $ =\frac{1087.5}{18}\approx Rs.60 $
