CP of 2/5th land = (96000×2)/5 = 38400
SP on loss 6% = CP - loss
                         = CP (1 - 6/100)
                         = (38400×94)/100
                         =Rs 36096
for gaining 10% on whole
SP= CP + 10% of CP
    =96000 + (10×96000)/100
    = 96000 + 9600
SP = Rs 105600
SP of 2/5th land = Rs 36096
SP of 3/5th land should be Rs (105600 - 36096) = Rs 69504
CP of 3/5th land = (96000×3)/5 = Rs 57600
gain = Rs (69504 - 57600) = Rs 11904
gain % = (11904×100)/57600 = 20.6%

Step-by-step explanation:

C.P of the total land => Rs 96000

C.P of th part of the land:-

=> 96000 × 2/5

=> 19200 × 2

=> 38400

S.P on loss 6% :-

=> C.P × 100 - loss

=> 38400 × 100 - 6/100

=> 384 × 100 - 6

=> 384 × 94

=> 36096

For gaining 10% on whole:-

=> S.P = C.P + 10% of C.P

=> S.P = 96000 + 10 × 96000/100

=> S.P = 96000 + 10 × 960

=> S.P = 96000 + 9600

=> S.P = Rs 105600

:-S.P of th part of the land=> Rs 36096

:-S.P of th part of the land should be Rs

=> 105600 - 36096

=> Rs 69504

:- C.P of th part of the land

=> 96000 × 3/5

=> 19200 × 3

=>Rs 57600

:-Gain of the total land:-

=> S.P - C.P

=> 69504 - 57600

=> Rs 11905

:- Gain% of the total land:-

=> 11904 × 100/57600

=> 11904/576

=> 5952/288

=>2976/144

=>1488/72

=>744/36

=>372/18

=>186/9

=>62/3

=> 62
