Book value of investments = ₹140000
Ram took over investments at ₹8100 which is book value less 10%
Lets calculate book value of investments took over by Ram.
Book value X (100- discount) = Investment took over by Ram
Book value x (100 -10) = 8100
Book value = 8100 x 100/90
                  = ₹9000
Remaining value of investments = 140000 - 9000
                                                   = ₹131000
This is taken over by Mohan at 90% of book value less ₹900.
Book value of investment = ₹131000
90% of investment = 131000 x 90/100
                              = ₹117900
Take over by Mohan = 117900 - 900
                                 = ₹117000
