The net money the farmer will get
= Rs. 39,500
Explanation:
The farmer bought 5 kg seeds of rice at Rs. 100 per kg.
Cost price = 5 × 100 = Rs. 500
And he plants them and harvests 1000 kg of rice grains for sale, which he sells for Rs. 40 per kg
Selling price = 1000 × 40 = Rs. 40,000
The farmer's net profit
= (Selling Price) - (Cost Price) = 40,000 - 500 = Rs. 39,500
