Let the cost price of the article be 100y.

Then, Marked Price = 100y + 25% of 100y = 125y

Given, Profit = 100y × 5.5% = 5.5y

Discount = MP – SP = 125y – (100y + 5.5y) = 19.5y

Thus, Discount (in %) =  = 15.6%

Let the cost price of TV be 100x.

Selling Price if 8% gain is to be earned = 100x + (100x) × 8% = 108x

Selling Price if 15% gain is to be earned = 100x + (100x) × 15% = 115x

However, difference between both the selling prices = Rs. 714

115x – 108x = 714

7x = 714

x = 102

Therefore, Cost Price = 102 × 100 = Rs. 10200

And Selling Price for 18% profit = 10200 + 10200 × 18%

= 10200 + 1836

= Rs. 12036

Let the Cost Price of article be x.

Then, Marked Price = (x) + (x) × 25% = 1.25x

Sale Price = Marked Price – Discount

= (1.25x) – (1.25x) × 10%

= 1.25x - 0.125x = 1.125x

Profit Percentage =

=  = 12.5%

We know that:

 cp =

 cp = 800 RS.

Given:

Marked Price of computer = Rs. 34400

Selling Price of computer = 34400 – (34400 × 12%) = Rs. 30272

And Cost Price of computer =  = Rs. 27520

Profit, if the retailer does not allow any discount = 34400 – 27520 = Rs. 6880

Therefore, profit percentage in above case =  = 25%

Let CP of the article = Rs x

According to question

Loss% = profit%

⇒

⇒

⇒

⇒ x = 290

Cost price of article = Rs. 290

Selling price of article = Rs. 275

Loss= CP-SP =Rs. 290 – Rs. 275 = Rs. 15

Loss% =

Let the marked price and the selling price of an article be Rs. 5x and Rs. 3x, respectively.

Discount = MP – SP

= 5x – 3x

= Rs. 2x

Discount percentage = = 40%

(MP = Marked price, SP = Selling price)

Let the cost price of A be x and B be y.

Then x + y = Rs.1734

And 0.84x = 1.2y

 =

Therefore, x = 1734 ×  = Rs. 1020

Hence, cost price of A is Rs. 1020

Profit (in %) on A (SP = Rs. 1147.50) =

=  = 12.5%

Let cost price of article = 100 unit

If Gain = 10%

Then Selling price of article = 100 unit + 10 unit = 110 unit

If Loss = 3%

Then Selling price of article = 100 unit + 3 unit = 97 unit

Reduction in the selling price of article = 110 unit – 97 unit = 13 unit

According to the question,

13 unit → Rs. 39

1 unit → Rs. 3

100 unit → Rs. 300

So, the original price of the article = Rs. 300

Let the cost price of an article be Rs. x.

Then, selling price in case of profit of 20% = x + (x) × 20% = 1.2x

And selling price in case of profit of 30% = x + (x) × 30% = 1.3x

Now, as per question

1.3x – 1.2x = 8

0.1x = 8

x =  = 80 = Cost Price of 1 article

Therefore, Cost price of 16 such articles = 16x = 16 × 80 = Rs. 1280
