Question

a man buy a plot of land at 360000 he sell one third of plot sold at a loss of 20 percent again he sell one third of plot left at a profit of 25 percent at what price should he sell the remaining plot in order to get a profit of 10 percent on the whole do good rough work also

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.
