Question

यदि विक्रय मूल्य दोगुना कर दिया जाए तो लाभ तीन गुना हो जाता, तब लाभ प्रतिशत क्या होगा?​

Answer 1

The profit percentage would be 100%

Step-by-step explanation:

Let us consider cost price is x and selling price is y,

We know that,

Profit, P= SP - CP

P = y - x   .......(1)

According to the question,

If SP = 2y, profit = 3P

3P = 2y - x

From equation (1),

3(y-x) = 2y - x

3y - 3x = 2y - x

3y - 2y = -x+ 3x

y = 2x    

⇒ P = 2x - x = x ............(2)

$Profit\%=\frac{Profit}{CP}\times 100$

$=\frac{P}{x}\times 100$

From equation (2),

$Profit\%=\frac{x}{x}\times 100=100\%$
