Here P= Rs. 12,000 , R= 15%

T = Money kept for the No of days divided by 365

Jan (31-13) = 18 days

Feb = 28 days

March = 31 days

April = 30 days

May = 31 days

June = 8 days

Total = 146 days

T = years

S.I =

= years

= Rs. 720

A = 12000 + 720 = Rs. 12720

Mohan paid Rs. 12,720 to the money-lender to clear his debt.

A) Rs. 22.5 | B) Rs. 2.5 |

C) Rs. 202 | D) Rs. 25 |

Explanation:

We know that I = PTR/100

=> P = 20250/4.5 = 4500

Now, new Interest at 5% = 4500x1x5/100 = 225

Now the additional amount = 225 - 202.5 = Rs. 22.5

A) 240 paise | B) Rs. 1.40 |

C) Rs. 2.20 | D) Rs. 3 |

Explanation:

I = PTR/100

I = 25 x 4 x 0.03/100

I = 0.03 x 100 = 300 Ps = Rs. 3

A) 45/7 % | B) 50/9 % |

C) 51/7 % | D) 47/ 9 % |

Explanation:

Let sum = S. Then, amount = 7S/6

S.I. = 7S/6 - S = S/6; Time = 3 years.

Rate = (100 x S) / (S x 6 x 3) = 5 5/9 = 50/9 %.

A) Rs. 580 | B) Rs. 480 |

C) Rs. 550 | D) Rs. 470 |

Explanation:

Let the sum be Rs. P. Then,

= 510

P[ - 1] = 510.

Sum = Rs. 1920

So, S.I. = (1920 x 25 x 2) / (2 x 100) = Rs. 480

A) Rs.8000 | B) Rs.6500 |

C) Rs.7500 | D) Rs.5000 |

Explanation:

Where d is difference, r is rate of interest.

=> (48 x 100 x 100) / 8 x 8 = Rs.7500
