Question :    What is the cost price; if a trader earns a profit of 295% by selling some articles for $22949.50?

Correct Answer  5810

Solution & 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) = $22949.5

And, the profit = 295%

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 + 295} × 22949.5

= ^{100 × 22949.5}/₃₉₅

= ^2294950/₃₉₅ = 5810

Thus, the Cost Price (CP) = $5810 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 = 295%

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

= 295% of m

= 295% × m

= ²⁹⁵/₁₀₀ × m

⇒ Profit = ^{295 m}/₁₀₀

Calculation of Cost Price (CP)

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

⇒ 22949.5 = m + ^{295 m}/₁₀₀

⇒ 22949.5 = ^{100 m + 295 m}/₁₀₀

⇒ 22949.5 = ^{395 m}/₁₀₀

After cross multiplication, we get

22949.5 × 100 = 395 m

⇒ 395 m = 22949.5 × 100

⇒ m = ^{22949.5 × 100}/₃₉₅

⇒ m = ^2294950/₃₉₅ = 5810

⇒ m = 5810

Thus, the Cost Price (CP) = $5810 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) = $22949.5

And, the profit = 295%

Then, the Cost Price (CP) = ?

Let Cost Price (CP) = 100

Thus profit = 295% of 100 = 295

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

⇒ Sale Price (SP) = 100 + 295

⇒ Sale Price (SP) = 395

∵ If the Sale Price (SP) is 395, then the Cost Price (CP) = 100

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

= ¹⁰⁰/₃₉₅

∴ If the Sale Price (SP) is 22949.5, then the Cost Price (CP)

= ¹⁰⁰/₃₉₅ × 22949.5

= ^{100 × 22949.5}/₃₉₅

= ^2294950/₃₉₅ = 5810

Thus, the Cost Price (CP) = $5810 Answer

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

Given, the sale price (SP) = $22949.5

And, the profit = 295%

Then, the Cost Price (CP) = ?

SP = 395% of CP

⇒ SP = ³⁹⁵/₁₀₀ × CP

⇒ 22949.5 = ^{395 CP}/₁₀₀

After cross multiplication

⇒ 22949.5 × 100 = 395 CP

⇒ 395 CP = 22949.5 × 100

⇒ CP = ^{22949.5 × 100}/₃₉₅

⇒ CP = ^2294950/₃₉₅ = 5810

⇒ CP = $5810 Answer
