A) Rs. 1640 | B) Rs. 2500 |

C) Rs. 2160 | D) Rs. 3000 |

Explanation:

=> 60x5 : 36x6 : 75x3

=> 100 : 72 : 75

=> 72/247 x 7410 = Rs. 2160

A) Rs. 28,000 | B) Rs. 18,000 |

C) Rs. 14,000 | D) Rs. 8,000 |

Explanation:

Investments ratio is = 3:1

Time period ratio is = 2:1

As they are proportional to gain

------

Gain ratio of Vishal and raghu = 6:1

But given Raghu got Rs. 4000,

=? 1 ----- 4000

7 ----- ?

=> Rs.28,000

The total gain = Rs.28,000

A) 11 months | B) 9 months |

C) 7 months | D) 10 months |

A) Rs. 820 | B) Rs. 830 |

C) Rs. 840 | D) Rs. 850 |

Explanation:

Let the total amount in the partnership be 'x'.

Then A's share = x/3

B's share = x/4

C's share = x/5

D's share = x - (x/3 + x/4 +x/5) = 13x/60

A : B : C : D = x/3 : x/4 : x/5 : 13x/60 = 20 : 15 : 12 : 13

A's share in the profit of Rs. 2490 = 20 (2490/60) = Rs. 830.

A) Rs. 1100 | B) Rs. 500 |

C) Rs. 1200 | D) Rs. 700 |

Explanation:

Let the amounts to be received by P, Q and R be p, q and r.

p + q + r = 1200

p = 1/2 (q + r) => 2p = q + r

Adding 'p' both sides, 3p = p + q + r = 1200

=> p = Rs.400

q = 1/3 (p + r) => 3q = p + r

Adding 'q' both sides, 4q = p + q + r = 1200

=> q = Rs.300

r = 1200 - (p + q) => r = Rs.500.
