Krishna said: (Mar 20, 2011) | |

Given banker's discount(b.d) for 3/2 yrs = 558 then banker's discount(b.d) for 2 yrs = x x=(558*2)/(3/2) x=744 we know t.d=(b.d*100)/(100+(r*t)) 600=(744*100)/(100+(r*2)) Therefore, r=12% |

Help with this given total population 9000. If male increase by5% and female by 8% the population would be 9600. Find number of male and female? |

Mohan said: (Aug 23, 2015) | |

@Nandini. Let x = No of males, y = No of female. x+y = 9000. As males increased by 5% no of males become 1.05*x, female becomes 1.08*y there for 1. 05x+1.08y = 9600 by solving the above two equations you will get the answer. |

@Yashwanth. bd * 2/3/2. |

Why we can't calculate T.D for 3/2 years = Rs 450. B.D=558, T.D=450. So, Sum=B.DX T.D/(B.D-T.D), If we calculate, it comes out R=16% per annum. Please, tell me where is the mistake? |

What is true dicount? |

Ritu said: (Sep 26, 2018) | |

B.D = A*r*t1/100 ---> (1) and T.D. = A*r*t2/(100+rt2) ---> (2). Now as the amount or sum of money is same so from (1) A= B.D*100/(r*t1). From (2) A= T.D*(100+r*t2)/(r*t2). Put values and compare both as 'A' is same. 558*100/(r*3/2) = 600*(100+2r)/(2r). 55800*2/3 = 300(100+2r). On solving 1860 = 1500 + 30r. r = 360/30. r = 12% answer. |
