An article was sold at a profit of 12%. If the cost price would be 10% less and selling price would be Rs. 5.75 more, there would be profit of 30%. Then at what price it should be sold to make a profit of 20%?

The article should be sold at Rs. 138 to make a profit of 20%.

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

Scenario 1: Actual Sale

  • Selling price (SP1) = Rs. (x + 12% of x) = Rs. 1.12x (Profit of 12%)

Scenario 2: Hypothetical Sale with Lower Cost Price and Higher Selling Price

  • New Cost Price (CP2) = Rs. (x – 10% of x) = Rs. 0.9x (10% less than original CP)
  • New Selling Price (SP2) = Rs. (1.12x + 5.75) (Rs. 5.75 more than original SP)
  • Profit in Scenario 2 = 30%

Relating the Scenarios:

We know that profit in Scenario 2 is 30%. We can express this as:

(SP2 – CP2) / CP2 = 30/100

Substituting the expressions for CP2 and SP2:

[(1.12x + 5.75) – 0.9x] / 0.9x = 30/100

Simplifying the equation:

0.22x + 5.75 = 0.27x

Solving for x (cost price):

0.05x = 5.75

x = 115

Scenario 3: Selling Price for 20% Profit

We now know the actual cost price (x = Rs. 115). To achieve a 20% profit, the selling price (SP3) needs to be:

SP3 = CP3 + 20% of CP3

SP3 = 115 + (20/100) * 115

SP3 = Rs. 138

Therefore, the article should be sold at Rs. 138 to make a profit of 20%.

How to Calculate Profit Percentage?

To calculate the profit percentage, you need to know the profit and the cost price of an item. Once you have those two values, you can use the following formula:

Profit Percentage = (Profit / Cost Price) * 100%

Here’s a step-by-step guide on how to calculate the profit percentage:

  1. Determine the cost price (CP) of the item. This is the amount of money you spent to acquire or produce the item.
  2. Determine the selling price (SP) of the item. This is the amount of money for which you sold the item.
  3. Calculate the profit (P) by subtracting the cost price from the selling price: Profit = SP – CP.
  4. Use the profit and the cost price to calculate the profit percentage using the formula mentioned above.

Here’s an example:

Let’s say you bought an item for $50 and sold it for $80.

  1. Cost Price (CP) = $50
  2. Selling Price (SP) = $80
  3. Profit (P) = SP – CP = $80 – $50 = $30
  4. Profit Percentage = (Profit / Cost Price) * 100% = ($30 / $50) * 100% = 0.6 * 100% = 60%
