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 |

C.P = 100.
S.P = 200(i.e S.P doubled).
Profit = S.P - C.P.
=>200-100 = 100.
Profit % = (profit*100)/C.P.
= (100*100)/100.
= 100.
S.P = 200(i.e S.P doubled).
Profit = S.P - C.P.
=>200-100 = 100.
Profit % = (profit*100)/C.P.
= (100*100)/100.
= 100.

PROFIT = 3(Y-X)= (2Y-X)
= 3Y-3X-2Y+X
= 1Y-2X
(i.e)Y=2X : Profit = (Y-X)(i.e) =(2x-x)=Rs.x
Profit% = C.P/profitX100= X/X*100=100%.
FROM HERE EXPLAIN CLEARLY.

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.
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.

P = S.P - C.P.
Profit triples and S.P doubles.
3P = 2S.P - C.P.
3(S.P - C.P) = 2S.P - C.P.
So, S.P = 2C.P.
S.P/C.P = 2/1.
P = 1 / 1*100.
Then, 100%.
Profit triples and S.P doubles.
3P = 2S.P - C.P.
3(S.P - C.P) = 2S.P - C.P.
So, S.P = 2C.P.
S.P/C.P = 2/1.
P = 1 / 1*100.
Then, 100%.

LET,
C.P= 100.
PROFIT= x.
THEREFORE , S.P =100 + x.
AS PER THE QUESTION,
2 * S.P- C.P = 3 * PROFIT.
2(100+x)-100 = 3x
or, 200+2x-100 = 3x.
or, x = 100.
C.P= 100.
PROFIT= x.
THEREFORE , S.P =100 + x.
AS PER THE QUESTION,
2 * S.P- C.P = 3 * PROFIT.
2(100+x)-100 = 3x
or, 200+2x-100 = 3x.
or, x = 100.

Hey guys. We can also do like that.
Let the S.P = 100.
Then according to the question.
PROFIT = SP - CP that is,
300 = 200 - x.
x = 100.
Simple one.

Let CP be 100. Selling price is doubled so gain/ profit value= 100 Rs.
Gain%= (gain/ 100)* 100.
Apply the values then, Gain%= (100/100)* 100.
Gain%= 100.
Gain%= (gain/ 100)* 100.
Apply the values then, Gain%= (100/100)* 100.
Gain%= 100.

Assume CP = x then SP increase double of CP.
Then SP = 2x.
Formula for gain% = {(gain) X 100/CP}.
Then gain%= (x/x) X 100.
Then finally gain% = 100.
Then SP = 2x.
Formula for gain% = {(gain) X 100/CP}.
Then gain%= (x/x) X 100.
Then finally gain% = 100.

@ALL.
Let the cp -x.
Then the sp double-2x.
Then profit triple-3x.
Sp - cp =gain/loss.
2x - x = x,
Gain/cp * 100.
x/x * 100.
Then, we got 100%_ans.

If Suppose CP=1 and SP=2,
then gain=1,
Now if SP=4,
then gain=3,
Hence we can calculate profit% as,
Profit%=gain*100/CP=(SP-CP)*100/CP=(1*100)/1=100.
then gain=1,
Now if SP=4,
then gain=3,
Hence we can calculate profit% as,
Profit%=gain*100/CP=(SP-CP)*100/CP=(1*100)/1=100.
