Question

A man buys a plot of land at Rs 360000. He sells one of the plot at a loss of 20%.Again, he sell two - third of the plot left at a profit of 25%.At what price should he sell the remaining plot in order to get a profit of 10% on the whole

Answer 1

CP = 3600000.
To gain 10% on whole land, SP = 360000 + 10% of 360000 = Rs. 396000.
1/3 of the land sold on 20% loss.
SP of 1/3 land = (360000/3) - 20% of (360000/3) = Rs. 96000.
SP of 2/5 of the land = (360000 * 2)/5 + 25% of (360000*2)/5 = Rs. 180000.
Thus, SP of the remaining land = 396000 - 96000 - 180000 = Rs. 120000.
