150 kg of wheat is at Rs 7 per kg. 50 kg is sold at 10% profit. At what rate per kg the remaining need to be sold so that there is a profit of 20% on the total price?
Let remaining 100 kg at x%. so,
50 kg 100 kg
So (x-20)/10 = 50 kg/100 kg
Solve, x = 25%
100 kg costs = 100*7 = Rs 700
So at 25% profit SP of 100 kg is (125/100) * 700 = Rs 875
So SP of 1 kg = 875/100 = Rs. 8.75
