If selling price is doubled, the profit triples. Find the profit percent.
Answer: Option
Explanation:
Let C.P. be Rs. x and S.P. be Rs. y.
Then, 3(y - x) = (2y - x) y = 2x.
Profit = Rs. (y - x) = Rs. (2x - x) = Rs. x.

Please read the question carefully,
S.P. is doubled.
Profit triples.
Let C.P. = 10, S.P. =20, Profit =30.
Profit%= (S.P. - C.P. ) / (C.P. ) *100.
= (20-10) / (10) *100.
=10/10*100.
=100%.
SOLVED.

Let cost price = Rs 1.
Selling price doubled i.e = Rs 2.
Profit triples i.e = Rs 3.
Gain = SP-CP.
= 2-1.
= rs 1/-.
Profit% = gain*100/CP.
= 1*100/1 = 100.
*You take any number it will be true. !

Take an example.
Cost=10
Sale=20
Profit=10
Double the sale price
20 * 2 = 40.
Profit = 30 which is tripled.
Now find profit %.
Gain/cost * 100 = 30/10 * 100 = 300%.
Please correct me if I am wrong.
Cost=10
Sale=20
Profit=10
Double the sale price
20 * 2 = 40.
Profit = 30 which is tripled.
Now find profit %.
Gain/cost * 100 = 30/10 * 100 = 300%.
Please correct me if I am wrong.

Let cp = x, sp = y.
We know profit = profit.
y-x = y-x.
If sp is doubled then according to the condition profit gets tripled.
2y-x = 3(y-x).
y = 2x.
Then gain = 100*y-x/x = (2x-x)*100/x = 100%.

y-x = y-x.

P = SP - CP,
As per the question,
3P = 2SP - CP,
3P = SP +SP - CP,
3P = SP + P,
SP = 2P,
P% = 100.
Otherwise,
Sp = P + P,
SP = CP + P,
Hence CP = P,
By formula P% = (P/CP)*100
So, P%=100.

Hai,
Actually, %gain = (gain ÷ c.p) * 100.
From the above formula gain% does not depend upon s.p., it just depends upon gain only.
So in PB gain increased 3 times so the answer is 300% only.

Given S.P is doubled,
Let us think S.P = 100 and profit = 50.
Now S.P is doubled = 200.
C.P = 50 as C.P = S.P-Profit.
Profit = S.P - C.P.
=200 - 50.
= 150.
Profit is tripled as (50)(3) = 150.
Let us think S.P = 100 and profit = 50.
Now S.P is doubled = 200.
C.P = 50 as C.P = S.P-Profit.
Profit = S.P - C.P.
=200 - 50.
= 150.
Profit is tripled as (50)(3) = 150.

When you are doubling the selling price then why the cost is not increased in proportion to the same. How can you keep it fixed? Kindly explain.
And the equation be 2y - 2x instead to 2y - x.

If selling price is doubled, the profit triples. Find the profit percent.
Solve:
Here Take it as Ratio method.
Consider to 3:2.
Her Profit = 3.
Selling Price = 2.
3-2 = 1.
1 * 100 = 100.

Hai Ezhil,
profit = S.P -C.P
S.P = 2Y
C.P = X
PROFIT = 3(Y-X)= (2Y-X)
= 3Y-3X-2Y+X
= 1Y-2X
(i.e)Y=2X : Profit = (Y-X)(i.e) =(2x-x)=Rs.x
Profit% = C.P/profitX100= X/X*100=100%
profit = S.P -C.P
S.P = 2Y
C.P = X
PROFIT = 3(Y-X)= (2Y-X)
= 3Y-3X-2Y+X
= 1Y-2X
(i.e)Y=2X : Profit = (Y-X)(i.e) =(2x-x)=Rs.x
Profit% = C.P/profitX100= X/X*100=100%
