3.
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 |

Let 1st S.P = 100, profit - 1x, and 2nd S.P = 200,
If profit is tripled then it is 3x.
Therefore 3x-1x= 2x,
x = 200/2.
x = 100.
If profit is tripled then it is 3x.
Therefore 3x-1x= 2x,
x = 200/2.
x = 100.

Let c.p =100 rs , then s.p=200,
Profit = 200-100=100.
%profit = 100*100/100=100%,
Profit becmes three times i.e 100 * 3 = 300.
Profit = 200-100=100.
%profit = 100*100/100=100%,
Profit becmes three times i.e 100 * 3 = 300.

Simple, As we know;
P=Sp-Cp.
So,
3x=2X-Cp,
Cp=x,
So now SP=x.
Cp=x.
So p= x.
We know P/CPx100.
So the answer will be 100 %.
P=Sp-Cp.
So,
3x=2X-Cp,
Cp=x,
So now SP=x.
Cp=x.
So p= x.
We know P/CPx100.
So the answer will be 100 %.

What is the use of saying "Profit triples", it makes question very confusing. If S.P doubles then how can be profit triples?

If,
C.P=100.
S.p = 200,
Profit = 100.
If s.p doubles;
C. P=100,
S.p=400,
Profit=300.
Hence, profit % =100/100 * 100 = 100.
C.P=100.
S.p = 200,
Profit = 100.
If s.p doubles;
C. P=100,
S.p=400,
Profit=300.
Hence, profit % =100/100 * 100 = 100.

Here for profit % we need to take profit as 2y-x or 3(y-x) but you take it as y-x.
I think we assume profit has tripled.

Let C.P=x.
S.P doubles then,S.P=2x,
Gain = S.P-C.P (2x-x),
Gain% = Gain/C.P * 100,
= 2x-x/x * 100,
= x/x * 100,
= 100%.
S.P doubles then,S.P=2x,
Gain = S.P-C.P (2x-x),
Gain% = Gain/C.P * 100,
= 2x-x/x * 100,
= x/x * 100,
= 100%.

Let CP = x;
SP = 2x;
Profit = SP-CP;
Profit = 2x-x;
Profit = x;
Gain% = (gain*100/cp);
Gain% = (x*100/X);
Gain% = 100;
SP = 2x;
Profit = SP-CP;
Profit = 2x-x;
Profit = x;
Gain% = (gain*100/cp);
Gain% = (x*100/X);
Gain% = 100;

Let cp = x., then sp = 2x.
The profit is (sp - cp)/cp * 100.
(2x - x)/x * 100.
x/x * 100 = 100.
Therefore profit =100.
The profit is (sp - cp)/cp * 100.
(2x - x)/x * 100.
x/x * 100 = 100.
Therefore profit =100.

There is no need for calculating y=2x (its already given in the question).
Just calculates profit%=((2x-x)/x)*100=100%.
Just calculates profit%=((2x-x)/x)*100=100%.
