T.D means True Discount |

Sayan said: (Mar 6, 2012) | |

Can somebody please explain: - Present Worth=100*T.D/RT??? |

@Sayan. We have studied the formula for Simple interest na. S.I= (P.R.T) /100 where P=principal, R=Rate, T=Time. 100 is there because rate is specified as a percentage. Just cross multiply the equation P=[(S.I) *100/ (R. T) ] Here P, principal is nothing but the present worth & true Discount is similar to S. I in this case and hence the equation. |

What is True discount ? Is it principal ??? |

Simple method as for I know. T.D. =(B.G. x 100)/(R/T)= (24*100)/(10*2)=Rs.120. B.G=(T.D)^2/P.W => P.W= (T.D)^2/B.G. P.W= (120)^2/ 24 = 14400/24=600. If anyone knows better explanation? |

Someone please show the derivation. B.G. = (T.D.)*(T.D.)/P.W. or T.D. = B.G.*100 /(Rate*Time). |

What is meant by PW? |

Vincent said: (Jul 21, 2014) | |

What is present worth? |

How T.D. = B.G.*100/(Rate*Time)? |

Dhruv said: (Aug 2, 2015) | |

Can it be done through compound interest? |

Sukhsand Singh said: (Oct 24, 2015) | |

Is the answer correct? I mean B.G = B.D - T.D. Now, B.D = (PxRxT)/100. T.D = (PxRxT)/(100+ RxT). Now, R=10; T=2; B.G = 24. Solving this we get P = 720. Am I doing anything wrong? Appreciate the help. |

Sakthivel Mrsd said: (Nov 17, 2015) | |

T.D = B.G*100/R*T. = 24*100/10*2. T.D = 120. P.W = 100*T.D/R*T. = 12000/20. P.W = 600. |

What is B.G? Is this difference between true discount and bankers discount? |

Vijay said: (Oct 10, 2016) | |

What is true discount mean? |

Bhavadip said: (Aug 12, 2017) | |

True Discount and bankers discount in which lots of the discount. BD is Actually Simple Intrest And banker TD is After the discount. |

Habibur Rahman said: (May 23, 2018) | |

I really don't understand why has come TD here? I think p=SI/nr where p is the principle and it should be asked answer and it's 120. |

Harshita said: (Aug 22, 2018) | |

Why didn't we add 100 in the denominator? Please tell me. |

Vishakha said: (Oct 22, 2018) | |

What is the difference between BG and TD? |

Amruth said: (Jun 18, 2019) | |

According to the first problem. TD= B.D*100/ 100+R*T. Please explain. |

Bhaskar Reddy said: (Apr 6, 2020) | |

BD-TD=24, So Take BD in terms of TD I,.e BD=TD(100+rt)/100. Substitute in above and take TD as common& solve TD, You will get True discount 120, Take TD=PW*rt/100 basic formulae, We get PW as 600. |
