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

If we assume current SP to be Rs.100/- and then profit as x. Then,
SP Profit
100 x
200 3x

Therefore, 300x+200x=600x
Therefore, x=100. I guess this is an easier approach.

Assume C.P = x.
//Then selling price is double.

Means S.P = 2x.
Profit = (S.P - C.P).
So profit = 2x-x = x.

%Profit = prifit*100/C.P.
= x*100/x.
= 100.

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%.

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%.

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.

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%.

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.

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%.

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;
