Hi All,
Here T stands for Time or Number of Years.
Why T = 1/3?
Because we can write 4 months as 1/3 years. (Ref: 4/12 = 1/3)
Hope you understand. Have a nice day guys! |

420*15%*4/12 = 20
420-20 = 400 |

How comes this formula T.D. = B.D. x 100 / 100+(R*T)
Atually T.D = Amout*rate*time / 100+(R*T) |

Atually T.D = Amout*rate*time / 100+(R*T)
--------------------------------------------------------------------------------
B.D = amount*rate*time/100
T.D = (amount*rate*time/100)*100/100+(rate*time)
= amount*rate*time/100+(rate*time) |

Easy solution
15% rate is for one year so we have to cslculate for 1/3 so its become 5% of 15% 420*100/105=400 |
