A land broker purchases a land
for Rs.1,50,000 and sold for Rs
2,20,000. Find his gain percent. ​

Answer 1

Cost price of the land = 1,50,000

Cost price of one third of the land = 50,000

Selling price of one third of the land = 0.94 x 50,000 = 47000

Now total selling price to get 10 % gain = 1,50,000x 1.1 = 165000

Selling price of remaing two third of the land = 165000 - 47000 = 118000

Cost price of two third of the land = 100,000

Gain percent on two third of the land = 18,000x100/100000 = 18 % 

Hence he should sell at 18 % gain, remaining teo third of the land.
