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

9620

A) JxJ = KL | B) KxK= JL |

C) LxL = JK | D) JKL = 1 |

Explanation:

Let the Time be 'N' and Rate be 'R'

J = (K x NR)/100 K = (L x NR)/100

J/K = NR/100 K/L = NR/100

J/K = K/L

= JL

A) 4.58 % | B) 5.96 % |

C) 6.52 % | D) 4.98 % |

Explanation:

Difference in amount = 514 - 415 = 99

R = 5.96%

A) Rs. 316 | B) Rs. 251 |

C) Rs. 154 | D) Rs. 294 |

Explanation:
