Answer» Correct Answer - Option 4 : 100% Formula used: Profit = SP - CP Profit % = (Profit/CP) × 100 Here, SP → Selling price, CP → Cost price Concept used: Profit and the loss is always given on CP Calculation: Let the SP and CP be x and y respectively Profit = (x - y) Now, the S.P. is doubled, then the new S.P. is 2x New profit = (2x - y) According to the question: ⇒ 3(x - y) = 2x - y ⇒ 3x - 3y = 2x - y ⇒ x = 2y ----(1) Now, Profit = SP - CP ⇒ x - y = 2y - y = y ----(from eq (1)) Profit % = (Profit/CP) × 100 ⇒ (y/y) × 100 = 100% ∴ The profit is 100%

If selling price is doubled profit triples. Find profit percent.1. 200%2. 400%3. 50%4. 100%

Answer» Correct Answer - Option 4 : 100%

Formula used:

Profit = SP - CP

Profit % = (Profit/CP) × 100

Here, SP → Selling price, CP → Cost price

Concept used:

Profit and the loss is always given on CP

Calculation:

Let the SP and CP be x and y respectively

Profit = (x - y)

Now, the S.P. is doubled, then the new S.P. is 2x

New profit = (2x - y)

According to the question:

⇒ 3(x - y) = 2x - y

⇒ 3x - 3y = 2x - y

⇒ x = 2y ----(1)

Now, Profit = SP - CP

⇒ x - y = 2y - y = y ----(from eq (1))

Profit % = (Profit/CP) × 100

⇒ (y/y) × 100 = 100%

∴ The profit is 100%
