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 |

I can't understand that it is saying if the selling price is doubled then the profit triples which means 2y=3 (y-x). Please suggest to me.

Another simple method:
Cost price = x,
Sell price = 2x,
Profit% = (sp-cp/cp) *100,
Profit% = (2x-x/x) *100,
Let x be 1.
(1/1) *100,
= 100.
Cost price = x,
Sell price = 2x,
Profit% = (sp-cp/cp) *100,
Profit% = (2x-x/x) *100,
Let x be 1.
(1/1) *100,
= 100.

Let The c.p be x
A/c to prblm s.p is 2 times c.p i.e 2x
Profit =s.p-c.p.
==> 2x-x =x.
%p=(profit*100)÷c.p,
%p=( x*100)÷x,
%p=100.
A/c to prblm s.p is 2 times c.p i.e 2x
Profit =s.p-c.p.
==> 2x-x =x.
%p=(profit*100)÷c.p,
%p=( x*100)÷x,
%p=100.

Very short method.
Let CP = x
Sp is double = 2x
Gain=sp-cp = x
Gain = (100 * gain/CP),
= (100 * x/x),
= 100.
Let CP = x
Sp is double = 2x
Gain=sp-cp = x
Gain = (100 * gain/CP),
= (100 * x/x),
= 100.

Lets have C.P =100 ; S.P =200 ; Profit = 300 (since from question).
Profit =200 -100 = 100.
Profit % = 100 * 100/100.
= 100.
Profit =200 -100 = 100.
Profit % = 100 * 100/100.
= 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.
C.P = 100.
S.P = 200.
C.P - S.P = profit
= 100.
Then,
(100/100) * 100 = 100.
100percent profit is the right anaswer.

Here p=s.p-c.p,
3p=2s.p-c.p,
3(s.p-cp)=2s.p-c.p ---->(p=s.p-c.p),
s.p = 2c.p,
p% = s.p-c.p/c.p * 100,
= 2c.p-c.p/c.p *100,
= 100%.
3p=2s.p-c.p,
3(s.p-cp)=2s.p-c.p ---->(p=s.p-c.p),
s.p = 2c.p,
p% = s.p-c.p/c.p * 100,
= 2c.p-c.p/c.p *100,
= 100%.

C.P = x.
S.P = 2x.
P = 3x.
We know Profit = S.P-C.P.
So Here Profit = 2x-x = x.
We also know Profit% = P/C.Px100.
X/Xx100 = 100%.
S.P = 2x.
P = 3x.
We know Profit = S.P-C.P.
So Here Profit = 2x-x = x.
We also know Profit% = P/C.Px100.
X/Xx100 = 100%.

Cp = 1(assume).
Sp = 2(Doubled).
P = 3(Tripled).
G% = sp - cp/cp * 100,
((2-1)/1) * 100 = 100.
By solving we will get the answer.
Sp = 2(Doubled).
P = 3(Tripled).
G% = sp - cp/cp * 100,
((2-1)/1) * 100 = 100.
By solving we will get the answer.
