Question

a man buys a plot of land for 72000 rs. he sells one-third of the land at loss of 20%and two-fifth at a gain of 25%.At what price must he sell the remaining land so as to make an overall profit of 10%?

Answer 1

72000*1/3=24000
48000*2/5=19200
remaining=28800

overall profit=72000×110/100=79200

24000×80/100+19200×125/100+28800×A/100=72900
A=125

that mean 25%profit
