Important for :

1

A

Let the sum of money = x then interest = 5x – x = 4xSI = | P × R × T | , 4x = | X × R × 25 | , R = 16% |

100 | 100 |

CI on Rs. 12500 for 2 years @ 16% per annum

= 12500 | ( | 1 + | 16 | ) |
^{2} |
– 12500 = 4320 |

100 |

Hence, option A is correct.

2

E

Let the efficiency of A = 2x and the efficiency of B = x

A and B complete a piece of work in 21 days then the total units of work = (2x + x) × 21 units = 3x × 21 units

If A work at 37.5% more than his efficiency then A efficiency will become (100 + 37.5)% of 2x = 2.75x

If B works 25% less than his efficiency then his efficiency will become 75% of x = 0.75x

If they work together then the total units of work in one day = (2.75x + 0.75x) = 3.5x

The total time taken by them to do 3x × 21 units of work

= 3x × | 21 | = 18 days |

3.5 |

Hence, option E is correct.

3

D

Total probability = ^{8}C_{2} = 28

Probability that one is Onion and another one is Potato = ^{4}C_{1} × ^{4}C_{1} = 16

Hence, reqd. probability = | 16 | = | 4 |

28 | 7 |

Therefore, option D is correct.

4

C

Let the average weight of 10 persons is x kg

Then the sum of the weight of 10 persons = 10x kg

Let the Ram’s weight is R and Sohan’s weight is S then

Case I: When Ram comes in place of Mohan

10x – 55 + R = 10(x + 2.5)

R = 10 × 2.5 + 55 = 25 + 55 = 80 kg

Case II: When Sohan comes in place of Mohan

10x – 55 + S = 10(x + 3.5)

S = 35 + 55 = 90 kg

The average weight of Ram, Mohan, and Sohan= | 80 + 55 + 90 | = | 225 | = 75 kg |

3 | 3 |

Hence, option C is correct.

5

A

Ratio of profit of Mohan, Sohan and Sunil = 750 : 500 : 250 = 3 : 2 : 1Let their capitals be Rs. 3x, Rs. 2x and Rs. x respectively.

Then, 3x = 17400

x = | 17400 | = Rs. 5800 |

3 |

Hence, Sohan capital = 2x = 2 × 5800 = Rs. 11600

Therefore, option A is correct.
