A) 1% | B) 2% |

C) 4% | D) 0% |

Explanation:

loss % = ${\left(\frac{commongainorloss}{10}\right)}^{2}$ %

= (20/10)x(20/10)% = 4%

A) Rs. 7.46/kg | B) Rs. 8/kg |

C) Rs. 8.74/kg | D) Rs. 8.56/kg |

Explanation:

Let the selling price of the rice = Rs.P/kg

Now, according to the question,

1040 - 100p = 30p

=> p = 8/kg

Hence, the selling price of the rice = **Rs. 8/kg**

A) 20 | B) 24 |

C) 26 | D) 28 |

Explanation:

Let the total amount be **200** {L.C.M of 40 and 50}

Chacobar C.P. = 200/50 = **4**

Fivestar C.P = 200/40 = **5**

Remaining Money after petrol = [200 - 200×10%] = **180**

Remaining money after buying fivestars = [180 - 20×5] = **80**

So number of Chacobar she can buy =** 80/4 = 20**

A) 13% | B) 8.5% |

C) 9.5% | D) 11.25% |

Explanation:

The ratio of money she lended is

24000 : 16000 = 3 : 2

Let the rate of interest be R%

**8% R%**** **

** 10**

**3 : 2**

**R = 13%.**

A) 260/11% | B) 18.4% |

C) 22.5% | D) 100/7% |

Explanation:

When profit is calculated on Marked Price (M.P) then,

**C.P = M.P - P%**

Let M.P = 100

=> C.P = 100 - 30 = 70

But S.P = Rs. 80 as he gave 20% discount,

Now, Actual Profit = $\frac{80-70}{70}x100$

= **100/7 % **

A) Rs. 12,500 | B) Rs. 11,250 |

C) Rs. 12,750 | D) Rs. 11,680 |

Explanation:

Given that SP = Rs. 12000 - 10% = Rs. 10,800

Loss% = 4

We know that, **C.P = 100/(100 - Loss%) x 100**

=> 100/100-4 x 10800

=> 1080000/96

**C.P = Rs. 11,250**

A) 13.8 % | B) 11.4 % |

C) 12.5 % | D) 14.5 % |

Explanation:

10% profit at half plot = 600000/2 x 10/100 = Rs. 30,000

15% profit at remaining half plot = 600000/2 x 15/100 = Rs. 45,000

Now, total profit = 30000 + 45000 = 75000

Profit % = 75000/600000 x 100 = **12.5 %**

A) 16 | B) 15 |

C) 17 | D) 14 |

Explanation:

Given when she sells at Rs. 160 for 20 articles, she get 40% loss.

Then, to get 20% profit selling at Rs. 240 for let 'P' articles

=> $\frac{{\displaystyle \frac{160}{20}}}{60}=\frac{{\displaystyle \frac{240}{p}}}{120}$

=> 120 x 160 x P = 20 x 70 x 240

=> P = 15 articles.

A) Rs.1000 | B) Rs. 1020 |

C) Rs.1210 | D) Rs.1140 |

Explanation:

Cost price of the article is given by

= 400x100/(20+20)

= Rs.1000
