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 |

Assume cp = 1 and sp = 2 then profit = 1.
If sp double means sp = 4 then profit = 4-1=3(it became triple).
So,
Formula----> profit/cp * 100 = 1/1 * 100 = 100.
If sp double means sp = 4 then profit = 4-1=3(it became triple).
So,
Formula----> profit/cp * 100 = 1/1 * 100 = 100.

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.

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.

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 = 1(assume).
Sp = 2(Doubled).
P = 3(Tripled).
G% = sp - cp/cp * 100,
((2-1)/1) * 100 = 100.
Sp = 2(Doubled).
P = 3(Tripled).
G% = sp - cp/cp * 100,
((2-1)/1) * 100 = 100.

LET;
CP = 100Rs
SP = 200RS
Profit = 100Rs
Now the SP is doubled(2×200) = 400
then the profit could be (3×100) = 300
So, here clearly the profit(100) is tripled when the selling price is Doubled, with the profit of 100.
CP = 100Rs
SP = 200RS
Profit = 100Rs
Now the SP is doubled(2×200) = 400
then the profit could be (3×100) = 300
So, here clearly the profit(100) is tripled when the selling price is Doubled, with the profit of 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)

Cp = 1(assume).
Sp = 2(Doubled).
P = 3(Tripled).
G% = sp - cp/cp * 100,
((2-1)/1) * 100 = 100.
By solving we will get the answer.
Sp = 2(Doubled).
P = 3(Tripled).
G% = sp - cp/cp * 100,
((2-1)/1) * 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%.
