a. Rs. 600

b. Rs. 700

c. Rs. 800

d. Rs. 1200

**Answer:** c. Rs. 800

**Explanation:**

1 day work of A = | 1 | ; 1 day work of B = | 1 |

12 | 16 |

1 day work of A+B+C = | 1 | = 1 day work of A + 1 day work of B + 1 day work of C |

6 |

∴ 1 day work of C = | 1 | - ( | 1 | + | 1 | ) = | 1 |

6 | 12 | 16 | 48 |

Ratio of 1 day work of A, B and C = | 1 | : | 1 | : | 1 | = 4:3:1 ---------------- Multiplied by 48 |

12 | 16 | 48 |

∴ Share of income of A, B and C is also in ratio 4:3:1 respectively.

Share of C = | 1 | x Total Amount = | 1 | x 6400 = Rs. 800 |

4+3+1 | 8 |

a. Rs. 1500

b. Rs. 2500

c. Rs. 5000

d. Rs. 7500

**Answer:** b. Rs. 2500

**Explanation:**

Total work of M = 1day work of M x 15 days = | 1 | x 15 = | 1 |

30 | 2 |

Total work of N = | 1 | x 15 = | 1 |

45 | 3 |

∴ Total work done by M and N = | 1 | + | 1 | = | 5 |

2 | 3 | 6 |

Remaining work = 1 - | 5 | = | 1 | = This is done by O |

6 | 6 |

Share of O = Total work done by O x Total Amount = | 1 | x 15000 = Rs. 2500 |

a. Rs. 150

b. Rs. 300

c. Rs. 450

d. Rs. 900

**Answer:** a. Rs. 150

**Explanation:**

Wages for 1 day for both = | Rs.2700 | = Rs. 900 |

3 |

If you work more you get proportionately more money

So man gets 5 times more money than boy.

∴ Ratio of wages of 1 day of man to wages of 1 day of son is 5:1

Daily wage of son = | 1 | x Wages for 1 day for both = | 1 | x 900 = Rs. 150 |

5+1 | 6 |

a. 45 Days

b. 55 Days

c. 64 Days

d. 75 Days

**Answer:** b. 55 Days

**Explanation:**

Let Prateek be absent for K days.

So, he worked for (100-K) days and got Rs. 840

He was fined for K days hence, his fine = Rs. 24 x K = 24K

∴ 840 = (100-K) x Rs. 48 - 24K

∴ 840 = 4800 - 48K - 24K

**∴ K = 55 = Prateek was absent for these many days**

a. Rs. 24

b. Rs. 25

c. Rs. 29

d. Rs. 32

**Answer:** c. Rs. 29

**Explanation:**

Since, Girls and Boys earn the same. Let us treat them to be all Boys.

So, 3 Girls + 3 Boys = 6 Boys

Let Daily wages of → Men=M; Women=W and Boys=B

6M=8W and 4W=6B -----------------> (1)

Also, 6M+4W+8B = Rs. 26

∴ 8W + 4W + 8 x | 4W | = Rs.26 ----------->Substituting values of M and B from 1 |

6 |

∴ M = | 8W | = Rs. 2 = Daily wages of 1 man |

6 |

Also, B = | 4W | = Rs. 1 = Daily wages of 1 boy |
