A) 120 | B) 150 |

C) 170 | D) 180 |

Explanation:

Suppose there are all the pigeons then total no of heads are 340 and total no of legs are 680.

Now, since 380 (1060-680) legs are extra, it means there will be 190 (380/2) rabbits.As we know a rabbit has two extra legs than that of a pigeon.

number of rabbits =190

and number of pigeons = 340- 190 = 150

A) 10 | B) 15 |

C) 20 | D) 30 |

Explanation:

Let the three parts M, N, O.

Then, M:N = 2:3 and N:O = 5:8

= (5 x 3/5) : (8 x 3/5) = 3:24/5

M:N:O = 2:3:24/5

= 10:15:24 => N = 98 x 15/49 = 30.

A) 600 | B) 300 |

C) 150 | D) 75 |

Explanation:

1/2:1/3:1/4 = 6:4:3

As the difference is 3

=> 3/13x2600 = 600

A) 1 : 2 | B) 2 : 1 |

C) 3 : 1 | D) 1 : 3 |

Explanation:

6M + 3B = 4(1M + 1B)

6M + 3B = 4M + 4B

2M = 1B

M/B = 1/2

A) 18 : 24 : 11 | B) 9 : 15 : 1 |

C) 20 : 15 : 9 | D) 21 : 7 : 3 |

Explanation:

Given k : l = 4 : 3

l : m = 5 : 3

Then k : l : m = 20 : 15 : 9

A) Rs. 159 | B) Rs. 96 |

C) Rs. 147 | D) Rs. 105 |

Explanation:

K : L : M = 100 : 45 : 30

= 20 : 9 : 6

Given L share is 27

=> 9 ------ 27

35 ------ ?

=> 105
