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 |

@Redhotpoker.
yes, you are right S.P is 2x but.
Gain% = SP-CP/CP * 100 ( SP = 2x and CP = x).
= 2x-x/x * 100,
= 100%.

Let CP=100 and SP=y
Profit = y-100.
If SP doubles, profit triples.
3(100-y) = 100-2y,
300 - 3 y = 100-2y,
y= 200.
SP is 200. CP was already taken as 100. So, profit is 100%.
Profit = y-100.
If SP doubles, profit triples.
3(100-y) = 100-2y,
300 - 3 y = 100-2y,
y= 200.
SP is 200. CP was already taken as 100. So, profit is 100%.

The formula for gain is CP-SP right?

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

Assume cp=100.
And sp = 200. (sp double).
Means profit = 100.
Profit %= profit * 100/ cp.
= 100 * 100/100,
=100.
And sp = 200. (sp double).
Means profit = 100.
Profit %= profit * 100/ cp.
= 100 * 100/100,
=100.

If the selling price is doubled.
It means 100% profit.

SP is double means 2x.
CP is Triple means 3x.
Diff is 1.
1P = 1.
100P = 100.
CP is Triple means 3x.
Diff is 1.
1P = 1.
100P = 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.
C.P = 100.
S.P = 200.
C.P - S.P = profit
= 100.
Then,
(100/100) * 100 = 100.
100percent profit is the right anaswer.

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%
