A trader bought a bag of 40 kg of basmati rice at Rs. 125 per kg and another bag of 60 kg at Rs. 150 per kg. He sold the entire stock at a profit of 20%. Find the selling price per kg.
Cost of basmati rice=
$$40\times125=5000$$
The cost of basmati rice is 5000.
Cost of another bag=$$60\times150$$
=9000.
The cost of another bag is 9000.
Total cost price=5000+9000
=14000.
Profit = 20%
Hence SP = $$1.2 \times 14000 = 16800$$
The selling price is 16800.
Total weight = 100kg
The selling price per kg is Rs.168
