20% discount on 28,800 is calculated as:

Discount = 28,800 * 20/100 = 5,760

Price after discount = 28,800 - 5,760 = 23,040

Explanation

• Calculate the price after the first discount of 20%:

Price after first discount=P×(1−0.20)=P×0.80

• Calculate the additional 10% discount on the already discounted price:

Price after additional discount=Price after first discount×(1−0.10)=(P×0.80)×0.90

• Simplify the calculation:

Explanation

To find the selling price after a 15% discount,

1: Calculate the discount amount:

Discount=Original Price×  15/ 100  =200×0.15=30

2: Subtract the discount from the original price:

Selling Price=Original Price−Discount=200−30=170

So, the selling price is $170.

Explanation

To find the cost of one pen, divide the total cost by the number of pens:

Cost of one pen = Total cost /Number of pens

Given:

Total cost for 5 pens = 125 rupees

Number of pens = 5

Cost of one pen= 125rupees / 5

Cost of one pen=25rupees

So, the cost of one pen is 25 rupees.

Explanation

The fruit seller initially had 35 mangoes.

He sells 12 mangoes to one customer and 8 mangoes to another customer.

To find out how many mangoes he has left, we subtract the total number of mangoes sold from the initial number of mangoes.

Explanation

In this type of problem always loss occurs.

Use Formula,

% Final Loss = (%loss * %gain)/100 = (10 *10)/100 = 1% loss.

Net Graphic Change Method:

100 ==10% profit ==> 110 == 10% loss ==> 99.

100 become 99, so 1% of loss occurs.

Explanation

The formula to calculate profit margin ratio is:

Net income / Net sales

$24,000 / $400,000 = 6%

Formula is: 

Net profit ÷ total revenue  × 100

Explanation

To calculate the loss, we subtract the selling price from the buying price:

Loss = Buying Price - Selling Price

Loss = Rs. 60 - Rs. 40

Loss = Rs. 20

Explanation

Profit= Selling price - cost price = 7500 - 5000= 2500

Profit% = (Profit/Cost price) x 100 = (2500/5000) x 100 = 50%
