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.
 Profit % = |
 |
x | x 100 |  % = 100% |
| x |

Profit = C.P - S.P.
Example : C.P = X.
If selling price is doubled So S.P = 2X.
= X-2X = X.
C.P = X, S.P = X.
Profit Percentage = gain x 100 / C.P.
= X x 100 / X = 100%.
Example : C.P = X.
If selling price is doubled So S.P = 2X.
= X-2X = X.
C.P = X, S.P = X.
Profit Percentage = gain x 100 / C.P.
= X x 100 / X = 100%.

In this problem clearly mentioned the selling price is doubled & profit is tripled.
Let C.P = 1 than S.P = 2.
Profit = (S.P)-(C.P).
=2-1 = 1.
Profit% = 1*100 = 100%.
Let C.P = 1 than S.P = 2.
Profit = (S.P)-(C.P).
=2-1 = 1.
Profit% = 1*100 = 100%.

Can you explain me if selling price is doubled then how profit is thrice the cost price.
As we all know that
selling price=cost price+ profit. I am little bit confused.

assume sp=100 and profit = 100
If selling price doubles profit triples.
Sp = 100 * 2 = 200 and profit = 100 * 3 = 300.
Gain = 300 - 200 = 100.
Gain% = 100*100/100 = 100.
If selling price doubles profit triples.
Sp = 100 * 2 = 200 and profit = 100 * 3 = 300.
Gain = 300 - 200 = 100.
Gain% = 100*100/100 = 100.

SP = x;
CP = y;
p = (x-y)*100/y;
SP' = 2x;
P' = 3*P;
=> (2x-y)*100/y = 3*(x-y)*100/y;
=> x = 2*y;
=> SP = 2*CP;
=> P = 100%;
=> Profit Percent = 100%.
CP = y;
p = (x-y)*100/y;
SP' = 2x;
P' = 3*P;
=> (2x-y)*100/y = 3*(x-y)*100/y;
=> x = 2*y;
=> SP = 2*CP;
=> P = 100%;
=> Profit Percent = 100%.

Here we suppose.
CP = x.
Then SP = 2x (According to the Question. ).
Then Profit = SP - CP.
Profit = 2x-x.
Profit = x.
And Profit% = x*100/x.
Profit% = 100% Answer.
CP = x.
Then SP = 2x (According to the Question. ).
Then Profit = SP - CP.
Profit = 2x-x.
Profit = x.
And Profit% = x*100/x.
Profit% = 100% Answer.

The value of sp = 2x bcoz SP was doubled then cp=3x (cp was tripled).
pf = sp - cp
So the solution is:
pf = 2x - 3x = pf/100%.
=x = 1x/100%,
then x = 1/100,
Ans:100%.
pf = sp - cp
So the solution is:
pf = 2x - 3x = pf/100%.
=x = 1x/100%,
then x = 1/100,
Ans:100%.

gain=s.p-c.p.
let the c.p be 'x' and s.p be 'y'.
profit is=(y-x)
condntn is if s.p is doubled then only profit will be tripled.
3*profit=(s.p-c.p)
3(y-x)=(2y-x)
y=2x;
let the c.p be 'x' and s.p be 'y'.
profit is=(y-x)
condntn is if s.p is doubled then only profit will be tripled.
3*profit=(s.p-c.p)
3(y-x)=(2y-x)
y=2x;

Let cp =10 and sp=20.
Know sp doubles = 40.
And profit triples = 3p.
We know that p = sp - cp.
According to question.
3p = sp - cp.
3(40 - 10) = 40 - 30.
30 = 30.
Know sp doubles = 40.
And profit triples = 3p.
We know that p = sp - cp.
According to question.
3p = sp - cp.
3(40 - 10) = 40 - 30.
30 = 30.

P=s.p-c.p.
According to condition,
3P= 2(s.p)-c.p,
Solve the equations simultaneously.
We get.
s.p=2P.
c.p=P.
Now
P%=(s.p-c.p/cp) * 100.
Put values, we get;
P%=100.
