Govind, who is a dry land farmer from Shiralas has a 5 acre field. His family includes his wife, two children and his old mother. He borrowed one lakh twenty five thousand rupees from the bank for one year as agricultural loan at 10 p.c.p.a. He cultivated soyabean in x acres and cotton and tur in y acres. The expenditure he incurred was as follows : He spent Rs10,000 on seeds. The expenses for fertilizers and pesticides for the soyabean crop was Rs 2000x and Rs 4000x2 were spent on wages and cultivation of land. He spent Rs 8000y on fertilizers and pesticides and Rs 9000y2 for wages and cultivation of land for the cotton and tur crops.

Let us write the total expenditure on all the crops by using variables x and y. Rs 10000 + 2000x + 4000x2 + 8000y + 9000y2 

He harvested 5x2 quintals soyabean and sold it at Rs 2800 per quintal. The cotton crop yield was (5/3)y2 quintals which fetched Rs 5000 per quintal.

Best answer

Total income 

= income on soyabean crop + income on cotton crop + income on tur crop 

= Rs(5x2 x 2800) + Rs((5/3)y2 x 5000) + Rs(4y x 4000) 

= Rs(14000x2 + (25000/3)y2 + 16000y)
