Anu fixes the selling price of an article at 25% above its cost of production. If the cost of production goes up by 20% and she raises the selling price by 10% then her percentage profit is (correct to one decimal place):

  1. 14.6%
  2. 13.8%
  3. 15.2%
  4. 16.4%

Let cost price of the article be Rs. 100

Selling price of the article = 100 x 125/100 = Rs. 125

Profit = 125-100 = Rs. 25

New cost price of the article = 100 × (120/100) = Rs. 120

New selling price of the article = 125 x (110/100) = Rs. 137.5

New profit = 137.5 - 120 = 17.5

.. Profit percentage = (17.5/120) x 100 = 14.6%

A person sells an article at a profit of 12%. If he had purchased it for 12% less and sold it for Rs. 9 less, he would have gained 27%. What is the original cost price of the article?

  1. Rs. 4,500
  2. Rs. 4,000
  3. Rs. 4,250
  4. Rs. 3,750

Let the cost price of the article be Rs. 100.

Selling price would be Rs. 112.

New cost price (12% less) = Rs 88

New selling price (27% profit) = 127% of 88 = Rs. 111.76

Now, the difference between both selling prices = 112-111.76 = Rs. 0.24

When the difference is 0.24, CP = Rs. 100

When the difference is 9, CP = 100 × 9/0.24 = Rs. 3750

Hence the cost price of the article is Rs. 3750.

A shopkeeper gives two successive discounts of 20 % and 10 % on surplus stock. Further, he also gives a 5 % extra discount on cash payments. If a person buys a shirt from the surplus stock and pays in cash, what overall discount percent will he get on the shirt?

Let the marked price of the shirt be Rs. 1000 => Price after first discount = Rs. 1000 – 20 % of Rs. 1000 = Rs. 1000 – 200 = Rs. 800 => Price after second discount = Rs. 800 – 10 % of Rs. 800 = Rs. 800 – 80 = Rs. 720 => Price after cash discount = Rs. 720 – 5 % of Rs. 720 = Rs. 720 – 36 = Rs. 684 Therefore, total discount = Rs. 1000 – 684 = Rs. 316 => Overall discount percent = (316 / 1000) x 100 = 31.60 %

A dishonest shopkeeper used a faulty balance that balances when 11kg is one pan and 10kg is in the other. He sells after hiking the cost price of the product by 10%. If he cheats the farmer while buying and the buyer while selling through his faulty balance, find his actual gain percent in the whole transaction.

a. 33.1%                  b. 22%                                  c. 22.22%                d. 30%
