Question:     Find the cost price, if a dealer earns a profit of 245% by selling a plot for $16594.5


Correct Answer  4810

Solution And Explanation

Solution

Finding the cost price if the sale price and profit percent are known

The cost price (CP) can be found using the formula, algebraic method, using shortcut method, and taking the cost price as 100, 200, 300, 400, 500, or whatever you want.

Finding the cost price using the formula when the sale price and profit percent are known

Given, the sale price (SP) = $16594.5

And, the profit = 245%

Then, the Cost Price (CP) = ?

Formula to find the cost price when the sale price and profit percent are known

Cost Price (CP) = 100/100 + gain% × SP

Thus, the Cost Price (CP)

= 100/100 + 245 × 16594.5

= 100 × 16594.5/345

= 1659450/345 = 4810

Thus, the Cost Price (CP) = $4810 Answer

Finding the cost price (CP) using the Algebraic Method when the Sale Pric (SP) and the profit percent are given

Let the Cost Price (CP) = m

Here given profit = 245%

Calculation of Profit

Profit is calculated on cost price (CP)

Formula to find the Profit = Profit% of CP

Thus, profit on the cost price of m

= 245% of m

= 245% × m

= 245/100 × m

⇒ Profit = 245 m/100

Calculation of Cost Price (CP)

The Sale Price (SP) = Cost Price (CP) + Profit

⇒ 16594.5 = m + 245 m/100

⇒ 16594.5 = 100 m + 245 m/100

⇒ 16594.5 = 345 m/100

After cross multiplication, we get

16594.5 × 100 = 345 m

⇒ 345 m = 16594.5 × 100

⇒ m = 16594.5 × 100/345

⇒ m = 1659450/345 = 4810

⇒ m = 4810

Thus, the Cost Price (CP) = $4810 Answer

Finding the cost price (CP) using Unitary Method by taking the cost price (CP) is equal to 100 when the SP and the profit percent are given

Given, the sale price (SP) = $16594.5

And, the profit = 245%

Then, the Cost Price (CP) = ?

Let Cost Price (CP) = 100

Thus profit = 245% of 100 = 245

Thus, Sale Price (SP) = Cost Price (CP) + Profit

⇒ Sale Price (SP) = 100 + 245

⇒ Sale Price (SP) = 345

∵ If the Sale Price (SP) is 345, then the Cost Price (CP) = 100

∴ If the Sale Price (SP) is 1, then the Cost Price (CP)

= 100/345

∴ If the Sale Price (SP) is 16594.5, then the Cost Price (CP)

= 100/345 × 16594.5

= 100 × 16594.5/345

= 1659450/345 = 4810

Thus, the Cost Price (CP) = $4810 Answer

Shortcut Method to find Cost Price (CP) when SP and profit percent are known

Given, the sale price (SP) = $16594.5

And, the profit = 245%

Then, the Cost Price (CP) = ?

SP = 345% of CP

⇒ SP = 345/100 × CP

⇒ 16594.5 = 345 CP/100

After cross multiplication

⇒ 16594.5 × 100 = 345 CP

⇒ 345 CP = 16594.5 × 100

⇒ CP = 16594.5 × 100/345

⇒ CP = 1659450/345 = 4810

⇒ CP = $4810 Answer
