A shopkeeper has 100 kg of good grade rice and x kg of bad grade rice. He brought good and bad grade rice for Rs. 20 and Rs. 10 respectively. He can sell the good and bad grade rice at Rs. 30 and Rs. 13.5 respectively. Out of x kg, if he mixes y kg of bad grade rice with good grade, he will get a profit of 69 2/7% from total sale. If he mixes y/2 kg of bad grade rice with good grade, he will get a profit of 57.5%. What is the profit he would have got if he sold honestly? (in rupees)

Points to be remembered while dimensioning: 1. Dimensions are to be placed on the view which clearly expresses the relevant features. 2. Once a dimension is marked in one view, it should not be repeated in another view. 3. Dimensions are to be drawn from hidden lines. 4. Dimensions should be given from the baseline or centre line of a hole. Which of the above statements are correct?
