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 cost price is = C
AND selling price = S
SO profit is (S-C)
IF SELLING PRICE IS 2*S THEN PROFIT IS (2S - C)
NOW,3(S-C)=(2S-C),3S-C=2S-C,S=2C
PROFIT=2C-C=C , % OF PROFIT =C/C X 100= 100 %
AND selling price = S
SO profit is (S-C)
IF SELLING PRICE IS 2*S THEN PROFIT IS (2S - C)
NOW,3(S-C)=(2S-C),3S-C=2S-C,S=2C
PROFIT=2C-C=C , % OF PROFIT =C/C X 100= 100 %

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.

Suppose C.P is 100.
And in the question given S.P is doubled means S.P is 200.
And Profit is triples i.e. 300.
So, the formula is %profit = S.P-C.P/C.P*100.
= 200-100/100*100 = 100.
And in the question given S.P is doubled means S.P is 200.
And Profit is triples i.e. 300.
So, the formula is %profit = S.P-C.P/C.P*100.
= 200-100/100*100 = 100.

We know that SP = CP + profit........1.
Now given 2 SP = CP + 3 profit........2.
ON solving these equation we get that,
S.P = 2 profit.
Now in equation SP-CP/CP*100.
Answer is 100%.
Now given 2 SP = CP + 3 profit........2.

S.P = 2 profit.
Now in equation SP-CP/CP*100.
Answer is 100%.

SP = x;
CP = y;
p = (x-y) * 100 / y;
SP' = 2x;
P' = 3*P;
=> (2x-y) * 100 / y = 3 * (x-y) * 100 / y;
=> x = 2 * y;
=> SP = 2 * CP;
=> P = 100%;
=> Profit Percent = 100%.
CP = y;
p = (x-y) * 100 / y;
SP' = 2x;
P' = 3*P;
=> (2x-y) * 100 / y = 3 * (x-y) * 100 / y;
=> x = 2 * y;
=> SP = 2 * CP;
=> P = 100%;
=> Profit Percent = 100%.

Don't confuse with X & Y.
Simple method is:
SP is doubled so 200. Profit is triples so 300. Hence CP is surely be 100.
Then work out formula:
Gain = SP - CP ; 200 - 100 = 100%.

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

profit1 = sp-cp.
profit2 = 2sp-cp.
profit2 = 3times profit1,
2sp-cp = 3(sp-cp),
sp = 2cp.
Therefore profit % = (sp-cp)100/cp = (2cp-cp)100/cp,
cp will get cancelled,
profit% = 100.
profit2 = 2sp-cp.
profit2 = 3times profit1,
2sp-cp = 3(sp-cp),
sp = 2cp.
Therefore profit % = (sp-cp)100/cp = (2cp-cp)100/cp,
cp will get cancelled,
profit% = 100.

s.p = x.
c.p = y.
p = s.p - c.p =>x - y.
s.p is doubled = 2x.
p =2x-y.
profit is tripled 3(x-y) = p.
3(x-y) = 2x-y.
3x-3y = 2x-y.
x = 2y.
p= 2y-y => y.
p% = y/y *100 =>100%.
c.p = y.
p = s.p - c.p =>x - y.
s.p is doubled = 2x.
p =2x-y.
profit is tripled 3(x-y) = p.
3(x-y) = 2x-y.
3x-3y = 2x-y.
x = 2y.
p= 2y-y => y.
p% = y/y *100 =>100%.

We know that SP/CP=(100+G%)/100.
So as per given question.
SP1/SP2=(100+G1%)/(100+G2%).
==> SP/2SP=(100+G)/(100+3G).
==>1/2=(100+G)/(100+3G).
==>G=100.
So
Profit=100%.
So as per given question.
SP1/SP2=(100+G1%)/(100+G2%).
==> SP/2SP=(100+G)/(100+3G).
==>1/2=(100+G)/(100+3G).
==>G=100.
So
Profit=100%.
