Given Data: TD=90 Amount = 540 BD==? We know that Amount = BD*TD/BD-TD 540 = BD*90/BD-90 540BD-48600 = 90BD Answer = 108. Have a nice day:). |

Following is explanation: Given that, Face Value of Bill (F) = Rs. 540. True Discount (TD) = Rs. 90. Banker's Discount (BD) is to be found out, which is simple interest on Face Value of Bill (F), => BD = F*R*T/100. => BD = 540*R*T/100....equation (1). True Discount (TD) is simple interest on Present Worth (PW). => TD = PW*T*R/100. => 90 = PW*T*R/100. => 90/PW = T*R/100....equation (2). We know, PW = F/[1+(T*R/100)]. => PW*[1+(T*R/100)] = 540. => PW*[1+(90/PW)] = 540. => PW + 90 = 540. => PW = 540 - 90 = Rs. 450....equation (3). From equation (2) & (3), => 90/450 = T*R/100....equation (4). From equation (1) & (4), => BD = 540*90/450. => BD = Rs.108. Thanks. |

A simple way: P.W = Amount-TD. P.W = 450. B.G = (TD)^2/PW. B.G = 8100/450 = 18. B.G = 18. B.G = BD-TD. BD = B.G+TD. BD = 18+90. BD = 108. |

Thank you all for the given explanation. |

Anjum Bano said: (Mar 15, 2017) | |

In a simple way, By formula; Sum(face value) = 540 & TD = 90. We know that, F = (BD*TD)/(BD-TD). => 540 = (BD * 90)/(BD-90), => 6BD - 540 = BD. BD = 108 = Bankers discount. |
