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 C.P. --> x then.
S.P. --> 2x.
Profit = S.P.-C.P. = 2x-x = x.
Profit% = Profit\C.P.*100 = 100%.
S.P. --> 2x.
Profit = S.P.-C.P. = 2x-x = x.
Profit% = Profit\C.P.*100 = 100%.

C.P-S.P profit x y(y-x).
x 2y(2y-x) according to question. The profit 3 times increased if S.P became doubled this means profit has increase from earlier (profit) three times.
This implies 3 times of of old profit must be equal to new profit.
= 3(y-x) = 2y-x.
By solve y = 2x.
And profit is y-x/x*100 = 2x-x/x*100 = 100%.
x 2y(2y-x) according to question. The profit 3 times increased if S.P became doubled this means profit has increase from earlier (profit) three times.

By solve y = 2x.
And profit is y-x/x*100 = 2x-x/x*100 = 100%.

s-c=p....1.
Now 2s-c = 3p....2.
Solve this.
s = 2p....3.
So c=p.....4.
Now as asked that when sp is 2 times then calculate pf percentage.
So (2s-c/c)*100 = pf percent.
So put value in terms of p.
2s = 4p.....from....3.
So (4p-p)/p)*100 = pf percentage.
So pf percentage 300.
Now 2s-c = 3p....2.
Solve this.
s = 2p....3.
So c=p.....4.
Now as asked that when sp is 2 times then calculate pf percentage.
So (2s-c/c)*100 = pf percent.
So put value in terms of p.
2s = 4p.....from....3.
So (4p-p)/p)*100 = pf percentage.
So pf percentage 300.

Let 100rs be the sales cost (cp + profit).
By selling it for 200rs profit triples (cp + 3*profit).
200-100 = 2*profit.
Profit = 50.
Therefore cp = 50.
Profit % = (sales-cp)/cp% = 1000.
By selling it for 200rs profit triples (cp + 3*profit).
200-100 = 2*profit.
Profit = 50.
Therefore cp = 50.
Profit % = (sales-cp)/cp% = 1000.

If you do not understand any method or formulas, solution it helps you.
Let initially there are 20 articles with 5 each ones price.
20*5=100.
Increase double S. P of each article.
20*10=200.
Profit % = (200-100/100) *100 = 100%.

Why here 2y-x is done? As we are only doubling selling price which is y.

Suppose the cost is 10 and the selling price is 15 then the profit is 5 after all the selling price being double means 30 the profit being triple means 5+5+5=15. So our selling price is 15 or our profit is also 15 then the profit is 100 percent.

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.
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.

Its very simple.
C.P = x.
S.P = 2y.
Profit =3x.
3x.
(2y-x).
But 2y = S.P = C.P + Profit = x + 3x.
Now + we will solve + 3x.
------- * 100.
x+3x-x.
Left hand portion will cut all and remain 100.
Ya its hard but not that much only use + logic + hope + so you will get this.

Very simple and easy approach.
Let SP =10.
And profit be X. So CP = 10-X equation 1.
Now SP doubles means it became 20. And profit triples means it become 3X.
So now CP = 20-3X equation 2.
Now equate equation 1 and 2.
10-X = 20-3X.
X = 5 means it is profit.
Now with X we can calculation CP by any one equation.
Then profit percent = P*100/CP.
5/5*100 = 100%.
It is the easiest way to solve.
