Answer 1

Hi Friend,

Here is your answer,

Cost of land =480000
He has sold 2/5 land and amount he got =2×480000×0.94/5
 =180480
To gain 10% profit he has to get total of = 480000×1.1
 =528000
Selling 2/5 of land he has to get=528000-180480=347520
Cost of 2/5 land=480000×2/5=192000
Gain % =100×(34750-192000)/192000=34749

34749 is the correct answer!!

Answer 2

Cost of land = 480000

 sold 2/5 land and the amount he got = 480000 * 2/5

 

                                                                = 192000

Loss of 6% percent =  192000(1-6/100)

                                 = 192000(94/100)

                                 = 1920 * 94

                                 = 180480

To gain 10% profit  = 480000 * 1.1

            

                               = 528000

selling 3/5 of land = 528000 - 180480

                               = 347520

cost of remaining 3/5 land= 480000 * 3/5 = 288000

Gain % = 100 * (347520 - 288000)/288000 = 20.66

Hope this helps!
