Question

a man buys a plot of land at rupees 360000sells one third of a plot at loss of 20% again he sells two thirds of plot left at a profit of 25% at what price should he sell the remaining plot in order to get a profit of 10% of whole

Answer 1

Cost =  Rs 3, 60, 000.

cost of 1/3 of the plot = Rs 1,20,000.
loss due to its sale = 20% = Rs 24,000.

cost of the second 1/3 of the plot = Rs 1,20,000
Profit due to its sale = 25% = Rs 30,000.

Net profit to be gained on the overall sales = 10%  =  Rs 36, 000.
 
Profit to be gained from the sale of third part = Rs 36,000 - 30, 000 + 24,000
       = Rs 30,000

So Sale price for the last 1/3 of the plot = Rs 1,20, 000 + Rs 30, 000
       = Rs 1, 50, 000
