Hence, option C is correct.

C

Hence, option C is correct.

2

D

Initially, A's capital = Rs. xB's capital = Rs. | 3x | |

2 |

Ratio of the equivalent capitals of A and B for 1 month

= | ( | x × 10 + | 3x | × 2 | ) |
: |
( | 3x | × 8 + | 3x | × 4 | ) |

4 | 2 | 4 |

= | ( | 10x + | 3x | × 2 | ) |
: (12x + 3x) |

4 |

= 23 : 30

A's share = | 23 | × 53000 = ₹ 23000. |

53 |

Hence, option D is correct.

3

D

Annual profit = 157300A : B = 3 : 2 ⇔ 6 : 4

A : C = 2 : 1 ⇔ 6 : 3

A : B : C = 6 : 4 : 3

B's share = | 4 | × 157300 = 4 × 12100 = 48400/- |

13 |

Hence, option D is correct.

4

A

Ratio of amount invested by P, Q, R= 45k : 70k : 90k

= 9 : 14 : 18

Total profit = ₹ 164K

Q's share = | 14 | × 164k = 14 × 4k = ₹56k. |

41 |

Hence, option A is correct.

5

B

Profit earned by C = 1 – | ( | 1 | + | 1 | ) | = 1 – | 7 | = | 5 |

3 | 4 | 12 | 12 |

So,

5 | = 5,000 |

12 |

∴ Profit received by A = |
1 | × 12,000 = Rs. 4,000 |

3 |

Hence, option B is correct.
