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 |

If,
C.P=100.
S.p = 200,
Profit = 100.
If s.p doubles;
C. P=100,
S.p=400,
Profit=300.
Hence, profit % =100/100 * 100 = 100.
C.P=100.
S.p = 200,
Profit = 100.
If s.p doubles;
C. P=100,
S.p=400,
Profit=300.
Hence, profit % =100/100 * 100 = 100.

@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%.

SP = CP + P
If sp -> 2sp,
then p-> 3p.
sp - cp gives profit,
2(sp) - cp gives total profit which equal to 3p(profit) -> eqn 1
2(cp + p) - cp = 3p,
2cp + 2p -cp = 3p,
cp = p.
p->cp
p equals to cp, which is 100%.
If sp -> 2sp,
then p-> 3p.
sp - cp gives profit,
2(sp) - cp gives total profit which equal to 3p(profit) -> eqn 1
2(cp + p) - cp = 3p,
2cp + 2p -cp = 3p,
cp = p.
p->cp
p equals to cp, which is 100%.

I have a doubt, is the question asking to calculate profit before doubling the SP or after?
Let us assume SP = Rs 6, CP = Rs 3, Profit = Rs 3.
As per question new SP = Rs 12, CP will remain same Rs 3 , Profit = Rs 9 ( triple of previous).
in 1st case P% = P/CPx100 = 3/3 x100 = 100%.
in 2nd case P% = 9/3 x100 = 300%.
Please confirm what is specified by the question? Profit in 1st case or 2nd case. Please explain me.

The formula for gain is CP-SP right?

Option 1 is correct.
Explanation :
3p = 2cp-cp/cp.
3p = cp/cp.
p = 1/3.
p% = 100/3.
p% = 662/3.
Explanation :
3p = 2cp-cp/cp.
3p = cp/cp.
p = 1/3.
p% = 100/3.
p% = 662/3.

Let c.p be x.
Let s.p be y.
profit = s.p - c.p.
3(y-x) = 2y-x,
3y-3x = 2y-x,
y = 2x.
Profit% = s.p-c.p/c.p * 100.
Put y = 2x here,
3(2x-x) = 2(2x)-x/x * 100,
6x-3x = 4x - x/x * 100,
3x = 300,
x = 100.
Let s.p be y.
profit = s.p - c.p.
3(y-x) = 2y-x,
3y-3x = 2y-x,
y = 2x.
Profit% = s.p-c.p/c.p * 100.
Put y = 2x here,
3(2x-x) = 2(2x)-x/x * 100,
6x-3x = 4x - x/x * 100,
3x = 300,
x = 100.

C.P = x.
S.P = 2x.
P = S.P - C.P.
=> 2x - x = 3.
=> x = 3.
C.P = 3.
S.P = 6.
P = S.P - C.P.
= 6 - 3.
=3.
=> P = 3.
P%= P/C.P(100)
= 3/3 (100).
= 1(100),
= 100%.
P% = 100%.
S.P = 2x.
P = S.P - C.P.
=> 2x - x = 3.
=> x = 3.
C.P = 3.
S.P = 6.
P = S.P - C.P.
= 6 - 3.
=3.
=> P = 3.
P%= P/C.P(100)
= 3/3 (100).
= 1(100),
= 100%.
P% = 100%.

Let c.p=x
s.p=2x
Profit = s.p - c.p
Profit = 2x - x = x
Profit % = x*100/x = 100%
s.p=2x
Profit = s.p - c.p
Profit = 2x - x = x
Profit % = x*100/x = 100%

Please read the question carefully,
S.P. is doubled.
Profit triples.
Let C.P. = 10, S.P. =20, Profit =30.
Profit%= (S.P. - C.P. ) / (C.P. ) *100.
= (20-10) / (10) *100.
=10/10*100.
=100%.
SOLVED.
