A) 12% | B) 30% |

C) 50% | D) 60% |

Explanation:

Friends, we know we will need gain amount to get gain percent, right. So lets get gain first.

Let the cost price of 1 pen is Re 1

Cost of 8 pens = Rs 8

Selling price of 8 pens = 12

Gain = 12 - 8 = 4

Gain% = $\left(\frac{gain}{\mathrm{cos}t}\times 100\right)$% = $\left(\frac{4}{8}\times 100\right)$% = 50%

A) 36.333% | B) 33.666% |

C) 33.333% | D) 36.666% |

Explanation:

Cost of 4 mangoes = Rs. 6

Cost of 1 mango = Rs. 6/4 = Rs. 1.5

Now, Selling Price of 4 mangoes = Rs. 4

Selling Price of 1 mango = Rs. 4/4 = Rs. 1.0

- We observe that,
**S.P < C.P**

Hence, the shopkeeper incurs a loss.

Required **loss% = loss/C.P x 100**

Loss = 1.5 - 1 = 0.5

C.P = 1.5

Loss% = (0.5/1.5) x 100

= (5/15) x 100

= 1/3 x 100

= 100/3

**= 33.333%.**

A) 35% | B) 40% |

C) 42% | D) 46% |

Explanation:

Tota profit percentage = (119 x 100/85) - 100 = 3400/85 = 40%

A) Rs. 11750 | B) Rs. 12550 |

C) Rs. 13650 | D) Rs. 11550 |

Explanation:

From the given data,

The cost price of the article = 5640 x 100/60 = Rs. 9400

The selling price of the article to gain 25% profit = 9400 x 125/100 = **Rs. 11750.**

A) Rs. 47 | B) Rs. 49.2 |

C) Rs. 48.5 | D) Rs. 50.3 |

Explanation:

Total cost of all varieties of mangoes = 20 x 2 + 40 x 3 + 50 x 5 = 40 + 120 + 250 = Rs. 410

Then, cost of 1 kg mangoes = 410/10 = Rs. 41

To get 20% profit,

The rate at which the mangoes should be sell = 120/100 x 41 = **Rs. 49.2**

A) Rs. 10.75 | B) Rs. 11.25 |

C) Rs. 12 | D) Rs. 13.50 |

Explanation:

Total quantity of sugar **= 45 + 30 = 75**

Gain or loss can be calculated as

9.75 x 75 - (30 x 9 + 45 x 10)

= 731.25 - 720

**= 11.25**

Hence, in the overall transaction, Rishi got **Rs. 11.25 gain.**

A) 35% | B) 28% |

C) 22% | D) 19% |

Explanation:

Given the cost price of the articles = Rs. 450

To get overall 20% gain,

Total Selling Price = (20/100) x 450 = 540

One third of the CP = 1/3 x 450 = Rs. 150

But given 1/3 of articles are sold at 10% loss

S.P of 1/3 of articles = 90% of 150

= 90 x 150/100 = 135

Then, S.P on remaining 2/3 goods must be

= 450 - 135 = 405 ...........(1)

CP on remaining goods

= 2/3 x 450 = 300 ............(2)

Profit = SP - CP = 405 - 300 = 105

Profit % = (105/300) x 100

= 35%.

A) loss of 24% | B) gain of 28% |

C) loss of 28% | D) gain of 20% |

Explanation:

Money invested by Rajan before 1 year was = Rs. 100000

Money in UK pounds @ 75 is = **100000/75 = 1333.33 Pounds**

Now, after 1 year invested amount was appreciated by 20%

=> **20% of 1333.33 = 266.66**

Total investment becomes = 1333.33 + 266.66 = 1600 Pounds

This 1600 Pounds @ Indian currency at 80 = **1600 x 80 = Rs. 1,28,000**

Hence, Rajan's investment of Rs. 1,00,000 becomes Rs. 1,28,000 in 1 year

Therefore, his profit % = **[(128000 - 100000)/100000] x 100 = 28%.**

A) 33.33% | B) 22.22% |

C) 11.11% | D) 1% |

Explanation:

Let the cost price of 1 article = Rs. 1

From the given data,

Then, the selling price of 1 article = 22/18 = 11/9

Then, Profit = SP - CP = 11/9 - 1 = 2/9

Required, profit % = Profit/CP x 100

= [(2/9)/1] x 100

= 200/9

= 22.222%.
