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 |

SP is double means 2x.
CP is Triple means 3x.
Diff is 1.
1P = 1.
100P = 100.
CP is Triple means 3x.
Diff is 1.
1P = 1.
100P = 100.

1st condition.
Let cp = x and sp=y
Profit = y-x.
2nd condition,
When sp is doubled,sp=2y.
Profit becomes triples, profit =3(y-x).
So,cp = sp - profit.
= 2y-3(y-x) = 3x - y.
As we know, cp at very condition will be the same.
3x-y = x.
2x = y.
Profit % = (profit/cp) * 100%,
= (y-x)/x * 100%,
= (2x-x)/x * 100%,
= 100%.
Let cp = x and sp=y
Profit = y-x.
2nd condition,
When sp is doubled,sp=2y.
Profit becomes triples, profit =3(y-x).
So,cp = sp - profit.
= 2y-3(y-x) = 3x - y.
As we know, cp at very condition will be the same.
3x-y = x.
2x = y.
Profit % = (profit/cp) * 100%,
= (y-x)/x * 100%,
= (2x-x)/x * 100%,
= 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%.

Simple way,
Here SP is doubled,
If normally 100%.
Double means = 200%,
profit is 200%-100% = 100%.
Here SP is doubled,
If normally 100%.
Double means = 200%,
profit is 200%-100% = 100%.

S.P = 2X => Double
C.P= X
P= (X-2X)3 => Triple
= 3X - 2X,
P= X.
Profit% = Profit/C.P × 100.
X/X ×100,
100.
Then, Profit% = 100.
C.P= X
P= (X-2X)3 => Triple
= 3X - 2X,
P= X.
Profit% = Profit/C.P × 100.
X/X ×100,
100.
Then, Profit% = 100.

Assume 40 is cost price,
80 as selling price,
120 is the profit.
As per the question, we have a formula for profit% = gain * 100/cost price = 40 * 100/100 = 100.
80 as selling price,
120 is the profit.
As per the question, we have a formula for profit% = gain * 100/cost price = 40 * 100/100 = 100.

Cp = x
Sp = 2X(doubled)
P = 3X(tripled)
P% = p/cp*100
Cp = sp - p
= 3x - 2x
= 1x = x.
P% = 1x = 1p( 1p = 1 profit).
Anything's 100 % is itself.
So, 100x=100p(100p= 100 profit)
Sp = 2X(doubled)
P = 3X(tripled)
P% = p/cp*100
Cp = sp - p
= 3x - 2x
= 1x = x.
P% = 1x = 1p( 1p = 1 profit).
Anything's 100 % is itself.
So, 100x=100p(100p= 100 profit)

Let CP=100 and SP=y
Profit = y-100.
If SP doubles, profit triples.
3(100-y) = 100-2y,
300 - 3 y = 100-2y,
y= 200.
SP is 200. CP was already taken as 100. So, profit is 100%.
Profit = y-100.
If SP doubles, profit triples.
3(100-y) = 100-2y,
300 - 3 y = 100-2y,
y= 200.
SP is 200. CP was already taken as 100. So, profit is 100%.

If,cp = x.
Sp = 2x.
Profit = 3x.
Then,sp>cp
2x - x
1st,2x - x = 3
X = 3.
2nd, profit % = 2x-x/x*100,
= 200x - 100x/x.
= 600-300/3.
= 300/3.
= 100%.
Sp = 2x.
Profit = 3x.
Then,sp>cp
2x - x
1st,2x - x = 3
X = 3.
2nd, profit % = 2x-x/x*100,
= 200x - 100x/x.
= 600-300/3.
= 300/3.
= 100%.
