A) Rs. 7500 | B) Rs. 8000 |

C) Rs. 8500 | D) Rs. 9000 |

Explanation:

Let B's capital be Rs. *x*.

Then,

=> 14*x* = 126000

*=> x* = 9000.

A) Rs. 20,000 | B) Rs. 10,000 |

C) Rs. 30,000 | D) Rs. 40,000 |

Explanation:

Let first part is 'K' and second part is 'L'

then K + L = 50000---------eq1

Total profit = profit on x + profit on y

7000 = (K x 10 x 1)/100 + (L x 20 x 1)/100

70000 = K + 2L-----------------------------------eq2

70000 = 50000 + L

so L = 20000 then K = 50000 - 20000 = 30000

first part on 10% is = Rs.30000

A) 11 months | B) 10 months |

C) 9 months | D) 8 months |

Explanation:

Let the total Profit be Z.

Ramu's profit share is 2/3 of profit (i.e 2Z/3)

Ravi's profit is (Z-2Z/3) =Z/3

Hence the profit ratio is , Ravi : Ramu = Z/3 : 2Z/3 = 1:2

Let total Capital be Rs.X and Ramu has contributed for Y months.Since Ramu's profit share is 2/3, his invest share will be 2/3 in capital.

Ravi's invest for 16 months / Ramu's invest for Y months = Ravi's profit share / Ramu's profit share

i.e. (X/6 x 16) / (2X/3 x Y) = 1/2

Solving the above equation, we get Y = 8.

So Ramu's money has been used for 8 months.

A) 11/3 | B) 2/13 |

C) 3/11 | D) 13/4 |

Explanation:

Let Veena paid x,

so Akshitha paid 2x/3 , and Lasya paid 2x,

So total bill paid is given by

x+(2x/3) +2x = 1, we get

i.e. x = 3/11

A) Rs. 75,000 | B) Rs. 85,000 |

C) Rs. 98,000 | D) Rs. 1,00,000 |

Explanation:

Deepa invested Rs.50,000 for 12 months, Rs.(50000 + 20000) for 12 months and Rs.(50000 + 20000 + 20000) for 12 months.

i.e, she invested Rs.50,000 for 12 months, Rs.70000 for 12 months and Rs.90000 for 12 months.

Sushma invested Rs. 70000 for 2 years; i.e, Rs.70000 for 24 months

And, Avanthi invested Rs.70000 for 1 year; i.e, Rs. 70000 for 12 months.

Their investing ratio:

Deepa : Sushma : Avanthi = (50,000 x 12 + 70000 x 12 + 90000 x 12):(70000 x 24):(70000 x 12)

= (25,20,000):(16,80,000):(8,40,000) = 252:168:84 = 3:2:1

Total profit for 3 years = Rs.3,00,000

Therefore, Sushma's share = Rs.(3,00,000 x 2 /(3+2+1)) = Rs.(3,00,000 x 2/6) = Rs.1,00,000.

A) Ram - Rs. 800, Raj - Rs. 900, Rakesh - Rs. 840 | B) Ram - Rs. 900, Raj - Rs. 800, Rakesh - Rs. 840 |

C) Ram - Rs. 840, Raj - Rs. 920, Rakesh - Rs. 840 | D) Ram - Rs. 800, Raj - Rs. 900, Rakesh - Rs. 940 |

Explanation:

Initial investment of Ram = Rs.2500.

After 2 months he withdraw Rs.1250 from his capital.

Therefore, we have, Ram invested Rs.2500 for 2 months and Rs.(2500-1250=) 1250 for 4 months.

Raj invested Rs. 2250 for 3 months and Rs.(2250-750=) 1500 for 3 months.

And, Rakesh invested Rs.3500 for 3 months;

Their investing ratio:

Ram:Raj:Rakesh = (2500x2 + 1250x4):(2250x3 + 1500x3):(3500x3)

= (10,000):(11,250):(10,500) = 1000:1125:1050 = 40:45:42

Total profit for 6 months = Rs.2540

Therefore, Ram's share = Rs.(2540 x 40/(40+45+42)) = Rs.(2540 x 40/127) = Rs.800

Raj's share = Rs.(2540 x 45/127) = Rs.900

Rakesh's share = Rs.(2540 x 42/127) = Rs.840
