Answer» Let the price of land = K. Then price of land after FIRST MIDDLEMAN = k + 20% of k = k + 0.2k = 1.2 k Price of land after second middle man = 1.2k + 20% of 1.2k = 1.2k + 0.24k = 1.44 k Price of land after third middle man = 1.44k + 20% of 1.44 k = 1.44k + 0.288k = 1.728k Hence, we have 1.728k = RS 345600 ⇒ k = 345600/1.728 ⇒ k = Rs 200000 |
