Let the sum(principal) received by A and B are x and y.

(1+r) = =

Then, =

Hence, the ratio in which the sum is divided =121:100

A) 6.5% | B) 6% |

C) 5% | D) 4.5% |

A) Rs. 1100 | B) Rs. 5500 |

C) Rs. 1400 | D) Rs. 4120 |

Explanation:

Let the sum be Rs.x. Then,

=> x =5500

sum = Rs. 5500.

So, S.I = Rs. .

A) Rs. 5422 | B) Rs. 5489 |

C) Rs. 3972 | D) Rs. 6145 |

Explanation:

Let p = Rs. 100.

Then, S.I is Rs. 50 and time = 5 years.

= 10% p.a.

Now, p = Rs. 12,000 , T = 3 years and R = 10% p.a.

C.I. = Rs. = Rs.

A) 2 | B) 4 |

C) 3 | D) 6 |

Explanation:

Let us assume Amount be 100 Rs and we calculate in CI

First year 60% of 100 = 60 amount (100+60) is 160

Second year 60% of 160 = 96 amount (160+96) is 256

Third year 60% of 256 =153.6 amount (256+153.6) is 409.6

Here the Amount of 100 Rs is quadrapled in 3 years.

One year contains 2 half years

Three year has 6 half years.

It takes 6 half years.

A) 4:5 | B) 5:4 |

C) 5:6 | D) can't be determined |
