– A farmer has 5 hectares of land and grows wheat on it. Given that the cost of sowing is 3 times the cost of seeds, the cost of labour is 150% higher than the cost of the sowing and the sum of all the other costs before selling the crop is 2 times the cost of labour. How many kg of wheat per hectare was produced if the farmer earned a profit of 150% (profit calculated on the total money spent in the agricultural process) and if it is given that the cost of seeds was rs. 7,000 and wheat sold by the farmer was at the rate of Rs. 18 per kg?
