A) Rs. 5989 | B) Rs. 6540 |

C) Rs. 7844 | D) Rs. 6789 |

Explanation:

Given C.I = 5984, R = 20% , T = 2yrs

5984 =

=> P = (5995x25)/11

P = Rs. 13625

Now S.I = PTR/100

SI = (13625 x 8 x 6)/100 = Rs. 6540

A) 5% | B) 6% |

C) 4% | D) 3% |

Explanation:

Given compound interest for 3 years = Rs. 1513.2

and simple interest for 5 years = Rs. 2400

Now, we know that C.I =

=> 1513.2 = ...........(A)

And S.I = PTR/100

=> 2400 = P5R/100 ..................(B)

By solving (A) & (B), we get

R = 5%.

A) Rs. 11828.80 | B) Rs. 19828.80 |

C) Rs. 9828.80 | D) Rs. 19328.80 |

Explanation:

Let the sum be Rs. P

P{ - 1 } = 2828.80

It is in the form of

P(8/100)(2 + 8/100) = 2828.80

P = 2828.80 / (0.08)(2.08)

= 1360/0.08 = 17000

Principal + Interest = Rs. 19828.80

A) Rs. 1911 | B) Rs. 1909 |

C) Rs. 1901 | D) Rs. 1907 |

Explanation:

P = Rs. 15225, n = 9 months = 3 quarters, R = 16% p.a. per quarter.

Amount =

= (15225 x 26/25 x 26/25 x 26/25) = Rs. 17126.05

=> C.I. = 17126 - 15625 = Rs. 1901.05.

A) 3 years | B) 4 years |

C) 2.5 years | D) 2 years |

Explanation:

> 2P or > 2

Now, (6/5 x 6/5 x 6/5 x 6/5) > 2.

So, n = 4 years.
