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%

@Poonam.

The statement is if s.p is doubled then profit triples and using the formula of profit in this statement, c.p.= X s.p.=Y formula of;

profit=s.p. - c.p. so, 3 ( profit = s.p - c.p )
3 (Y-X)=(2Y-X).

Let the C.P be Rs.100 and S.P be Rs.x, Then;
The profit is (x-100),
Now the S.P is doubled, then the new S.P is 2x,
New profit is (2x-100),
Now as per the given condition;
=> 3(x-100) = 2x-100.
By solving, we get;
x = 200.
Then the Profit percent = (200-100) * 100/100 = 100,
Hence the profit percentage is 100%.

Let me clear it;

LET THE CP BE Rs; x.
AND LET THE SP BE Rs y.

So, PROFIT = y - x.

But, HERE AS MENTIONED PROFIT TRIPLES AND SP DOUBLES;
SO,3(y-x) = 2y-x.
3y-3x = 2y-x.
y = 2x(SP).
PROFIT = 2x-x = x.
PROFIT % = x/x * 100=100(HERE X is profit and X is CP).

I think the answer is wrong.

2Sp = 2profit.
2sp = 2 (sp-cp),
3cp = 2sp,
Profit = 1.
Profit% = 50.

Let c.p=x.
s.p=2x.
Profit = s.p - c.p.
Profit = 2x - x = x.
Profit % = x*100/x = 100%.
