We know that,
Banker's Gain (BG) = Banker's Discount (BD) - True Discount (TD).
=> 270 = (F*T*R/100) - (PW*T*R/100).
=> 270*100/(T*R) = F - PW.
=> 270*100/36 = F - PW.
=> F - PW = 750.
=> F - [F/{1+(R*T/100)}] = 750.
=> F - [F/{(100+36)/100}] = 750.
=> F - [100F/136] = 750.
=> 136 F - 100 F = 750*136.
=> 36 F = 750*136.
=> F = 750*136/36.........equation (1).
From equation (1), Banker's Discount (BD) = F*T*R/100.
=> BD = 750*136*12*3/(100*36).
=> BD = 15*68 = RS. 1020.
Thanks.

270*100/12*3 = 6750 when added to 6750+270 = 7050.
This is the error in question.

TD = B. G*100/R*T.
TD = 27000/12*3.
TD = 750.
BG = BD-TD.
BD = BG+TD.
BD = 270+750.
BD = 1020.
TD = 27000/12*3.
TD = 750.
BG = BD-TD.
BD = BG+TD.
BD = 270+750.
BD = 1020.
