B.G. x 100 |  |
= Rs. | |

= Rs. 750. |
| R x T | 12 x 3 |

I = (PNR/100).
270 = (P*3*12)/100.
= 1020.
270 = (P*3*12)/100.
= 1020.

750 is a amount on which 12 % rate was calculated.
270 in 3 years. So Bankers gain is 270/3 = 90 for each year.
90 = 12% of Amount. So 90=12/100 of Amount. 90/12 =Amount. Amount = 750.
But this was the amount Banker had a profit of 90 each year. Not 270?
So, 750 + 90 = 840 for each year. Correct me.

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.

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

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.

TD means total discount.
BG is banker gain.
R is rate and T is time.
