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 = 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%.

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.

2sp = 3profit.
Ratio 2:3.
The difference between them 1.
Therefore 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%.

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%.

Let CP 100 and SP 200.
Profit sp-cp = 200-100 = 100
Gain% = profit/cp × 100.
So, 100/100 × 100 = 100%.
Profit sp-cp = 200-100 = 100
Gain% = profit/cp × 100.
So, 100/100 × 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.

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%.

Cp = 100 = x.
Sp = 200 = 2x.
P = sp - cp = 200 - 100,
or 2x - x = 100 or 1x,
P% = 1/100 * 100 = 100.
Sp = 200 = 2x.
P = sp - cp = 200 - 100,
or 2x - x = 100 or 1x,
P% = 1/100 * 100 = 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.
