Description : Vaishnavi purchased 35kg of wheat at the rate of Rs.19.50 per kg and another 35kg of wheat at a certain rate. She mixed the two and sold the entire quantity at the rate of the Rs.21.25 per kg and made 20%. Overall profit at what price per kg did she purchase the lot of another 35kg wheat?
Last Answer : Let the required price per kg be Rs'X' Then cost price of 70 kg wheat = Rs(35 * 19.50 + 35 * X) = Rs (682.5 + 35X) Selling price of 70kg wheat = Rs (70 * 21.25) = Rs.1487.5 Total cost ... 100/120=1239.58 35x= 1239.58-682.5=557.08 X=15.91 So the cost price of second lot is Rs15.91 per kg
