Important for :

C

The amount of 160000 is divided into two equal parts - 80000

Interest earned in the first scheme = 80000*(112/100)*(112/100) = 100352-80000= 20352

Interest earned in the second scheme = 80000*13*2/100 = 20800

Difference = 20800- 20352 = Rs. 448

The amount of 160000 is divided into two equal parts - 80000

When Rs. 80000 is compounded annually for 2 years at the rate of 12% interest. the effective rate of interest for two years becomes 25.44% (Kindly refer to Sub-details).

And that man invests half the part in another scheme offering 13% per annum at simple interest for 2 years, the interest become 26%.

Rate per cent difference = 26% – 25.44 = 0.56%

Required difference = 0.56% of 80000 = 448

---------------------------------------------------

We can calculate the effective rate of interest by applying the net% effect formula

= x + y + | xy | % |

100 |

Here, x = 12% and y = 12%

So, the effective rate of interest for two years will be as follows:

= 12 + 12 + | 12 × 12 | = 25.44% |

100 |

Hence, option C is correct.

C

Let the total capital in the business be 100xContribution of A = 60x and contribution of B = 40x

Let the time before withdrawal be x months

So time money product before withdrawal= A = 60xy and B = 40xy

After withdrawal Capital of A= 30x and B= 30x

So time money product after withdrawal = A= 30x(12 – y) and B = 30x(12 – y)

Total time money product of A = 60xy + 30x(12 – y)

Total time money product of B = 40xy + 30x(12 – y)

Now their ratio is 102 : 82

So we will equate them in the way

60xy + 30x(12 – y) | = | 102 |

40xy + 30x(12 – y) | 82 |

y will come out to be 5 months

Hence, option C is correct.

3

B

Let the present age of X be 4m and the present age of Y be 3mAlso, let us assume that they got married t years ago.

So, as per the question

(4m – t) | = | 5 |
....(1) |

(3m – t) | 3 |

(4m + 4) | = | 9 |
. ...(2) |

(3m + 4) | 7 |

Equation (2) is solvable as (1) has 2 variables. Thus, solving (2)

7 × (4m + 4) = 9 × (3m+4)

28m +28 = 27m +36

m = 8

Now using the value of m in (1) we get

(32 – t) | = | 5 |

(24 – t) | 3 |

t = 12 years

Hence, option B is correct.

4

D

The area of the ground is 40 × 50 = 2000mThe area of the circular area is | 22 |
× 14 × 14 = 616 m^{2} |

7 |

The remaining area = 2000 – 616 = 1384 m

The cost of laying tiles = 1384 × 50 = Rs. 69200

Hence, option D is correct.

5

B

Since there are 25 students in a class. 60% have an average of 60kg

Which means that 15 students have an average weight of 60kg

The other 10 students have weight of 33.33% less than that of the 60% students (Product Constancy)

So, it means their weight is 40kg

Total weight is (15 × 60) + (10 × 40) = 1300 kg

Hence, option B is correct.

Which means that 15 students have an average weight of 60kg

The other 10 students have weight of 33.33% less than that of the 60% students (Product Constancy)

So, it means their weight is 40kg

Total weight is (15 × 60) + (10 × 40) = 1300 kg

Hence, option B is correct.
