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%

Option 1 is correct.

Explanation :

3p = 2cp-cp/cp.
3p = cp/cp.
p = 1/3.
p% = 100/3.
p% = 662/3.

Let,
The cost price = 1.
And selling price = 2 (selling price is doubled),

Formula : Profit % = (sp - cp)/cp*100.
So, (2-1)/1 * 100.
Then profit % = 100.

Assume cp = 1 and sp = 2 then profit = 1.
If sp double means sp = 4 then profit = 4-1=3(it became triple).
So,
Formula----> profit/cp * 100 = 1/1 * 100 = 100.

SUPER EASY 1-LINE SOLUTION.
Suppose,

C.P =1;
S.P=2;
PROFIT=1;

when S.P doubled.

S.P =4; (Selling price doubled from 2 to 4)
PROFIT =3;(profit increased from 1 to 3)

GAIN% = P/CP *100.

1/1 *100 = 100%

Let,
C.P = 100.
S.P = 200.
C.P - S.P = profit
= 100.
Then,
(100/100) * 100 = 100.
100percent profit is the right anaswer.

SP is double means 2x.
CP is Triple means 3x.
Diff is 1.
1P = 1.
100P = 100.

Assume cp=100.
And sp = 200. (sp double).
Means profit = 100.

Profit %= profit * 100/ cp.
= 100 * 100/100,
=100.

1st condition.

Let cp = x and sp=y
Profit = y-x.
2nd condition,
When sp is doubled,sp=2y.

Profit becomes triples, profit =3(y-x).
So,cp = sp - profit.
= 2y-3(y-x) = 3x - y.
As we know, cp at very condition will be the same.
3x-y = x.
2x = y.

Profit % = (profit/cp) * 100%,
= (y-x)/x * 100%,
= (2x-x)/x * 100%,
= 100%.

Simple way,

Here SP is doubled,
If normally 100%.
Double means = 200%,
profit is 200%-100% = 100%.
