A) Rs 1 | B) Rs 1.33 |

C) Rs 1.5 | D) Rs 1.6 |

Explanation:

Recall it is based on inverse proportion or product constancy concept.

Reducion in price increase in amount

25% 33.33% = 4 oranges

It means original number of oranges = 4 x 3 = 12

original price of oranges = = Rs. 1.33

A) 22.77 | B) 25.77 |

C) 27.77 | D) 29.77 |

If the price of the oranges decreases by 10%, the woman would save 10% of the money that is Rs.50 to buy the same amount as before.Now in Rs50 she can buy 2 kg more, therefore the current price of 1 kg of oranges is Rs25.Now this current price is after 10% reduction.

Therefore, the original price =

A) 10% | B) 15% |

C) 20% | D) 25% |

Explanation:

Let the list price be Rs.100.

Therefore,the retailer is buying the products at Rs.60 and selling it to the customer at Rs.75, earning a profit of Rs.15.

Therefore, his percentage is = 25%

A) 6% | B) 8% |

C) 10% | D) 12% |

Explanation:

Let the shopkeeper buy 300g for Rs.300. Now he sells 100g for Rs.110, another 100g for Rs120, and the rest 100g for Rs94.

Therefore, the total amount he receives = Rs.110 + Rs.120 + Rs.94 = 324.

Therefore, the shopkeeper spends Rs.300 and gets back Rs.324.

Therefore, his profit percentage = % = 8%

A) Rs.720 | B) Rs.640 |

C) Rs.540 | D) Rs.480 |

Explanation:

SP = Rs.800 ; Profit = 25%

Now, CP = Rs.640

Loss = 25% = 25% of Rs.640 = Rs.160

Thus, SP = CP - Loss = Rs.640 - Rs.160 = Rs.480

A) 4% | B) 5% |

C) 6% | D) 8% |

Explanation:

SP of first article = Rs.1000

Profit = 20%

SP of Second Article = Rs.1000

Loss = 20%

So, Total SP = Rs.2000; Total CP = Rs.6250/3

As the CP is more than SP, he makes a loss.

Loss = CP - SP = (6250/3) - 2000 = Rs.(250/3)

So, Loss Percent = = 4%
