Important for :

1

A

Let the capacity of the tank = lcm of 18 and 20 = 180 litresEfficiency of P = | 180 | = 10 litres/hr |

18 |

Efficiency of Q = | 180 | = 9 litres/hr |

20 |

If there is no leak then the total time taken by (P + Q) to fill half of the tank

= | 90 | = | 90 | hrs |

10 + 9 | 19 |

When there is leak then according to the question, the total time taken by them

= | 90 | + 1 hr = | 109 | hrs |

19 | 19 |

Efficiency of (P + Q) + leak = | 90 |

109 | |

19 |

{because 109/19 hrs is taken by P, Q, and leak to fill half of the tank}

= 90 × | 19 | litres/hr = | 1710 | litres/hr |

109 | 109 |

We know that the efficiency of (P + Q) = (10 + 9) = 19 litres/hr

So, the efficiency of the leak

= 19 – | 1710 | = | 361 | litres/hr |

109 | 109 |

So the total time taken by the leak to empty the filled tank

= | 180 | = | 19620 | hrs = 54 | 126 | hrs |

361 | 361 | 361 | ||||

109 |

Hence, option A is correct.

2

C

Let the width of the rectangle = x cmThen, 300% of x = 51

x = 51 × | 100 | = 17 cm |

300 |

Perimeter of the rectangle = 2(length + width) = 2 × (51 + 17) = 136 cm

Perimeter of the square = (136 + 8) = 144 cm

The sides of the square = | 144 | = 36 cm |

4 |

The area of the square field with street = (36 + 20)

The area of the street = 3136 – 1296 = 1840 sq. cm

The total cost of constructing the street = 1840 × 25 = Rs. 46,000

Hence, option C is correct.

3

D

Total fare for 3 days = Rs. (500 + 600 + 700) = Rs. 1800/–According to their agreement,

Anjali has to pay = | 2 | × 1800 = 400/– |

2 + 3 + 4 |

Pooja has to pay = | 3 | × 1800 = 600/– |

2 + 3 + 4 |

Kriti has to pay = | 4 | × 1800 = 800/– |

2 + 3 + 4 |

Person | Amount Paid during the trip | Due amount according to ratio |

Anjali | 500 | 400 |

Pooja | 600 | 600 |

Kriti | 700 | 800 |

But we can see that Anjali paid 100/– more and Kriti paid 100/– less than the amounts they should have paid. Hence Kriti has to pay 100/– to Anjali.

Hence, option (D) is correct.

D

Let father’s age be x, and father’s father age be y.Then, ATQ,

7x = 3y or, y = | 7x |

3 |

Nine years ago,

ATQ,

(x – 9) = | 1 | (y – 9) |

3 |

Replacing the value of y, and simplifying, we get,

3 (x – 9) = | 7x | – 9 |

3 |

3 (3x – 27) = 7x – 27

9x – 81 = 7x – 27

2x = 81 – 27 = 54

x = | 54 | = 27 years |

2 |

father’s father’s age = | 7x | = 7 × 9 = 63 years |

3 |

father’s son’s age = (27)

Ratio of ages (in required sequence) = 63 : 3 : 27 = 21 : 1 : 9

Hence, option D is correct.

5

A

In the case of compound partnerships, the profits are shared in the ratio of capital invested. Here capital is a unit calculated as capital = (sum invested) × (time period)

Let the amounts initial amounts invested by A and B be 3t and t respectively. A later invested Rs. 2000 for 8 months and B invests Rs. 6000 for 6 months.

It is given that A's share is double of B's share:

24t + 72000 = 36t + 16000

12t = 56000

3t = 14000

Thus, A's initial investment will be = 3t = Rs. 14000

Hence, option A is correct.

∴ | A"s investment | = | 2 |

B"s investment | 1 |

∴ | 3t × 12 + 2000 × 8 | = | 2 |

t × 12 + 6000 × 6 | 1 |

∴ | 36t + 16000 | = | 2 |

12t + 36000 | 1 |

24t + 72000 = 36t + 16000

12t = 56000

3t = | 56000 |

4 |

3t = 14000

Thus, A's initial investment will be = 3t = Rs. 14000

Hence, option A is correct.
