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 |

Just take cp 100%.
Then sp=100%+profit.
2 times of sp = 200%+2p == cp+3 (p)here profit only triple not cost price(100% only).
200%+2p=100%+3p.
From that;
P=100%.
Then sp=100%+profit.
2 times of sp = 200%+2p == cp+3 (p)here profit only triple not cost price(100% only).
200%+2p=100%+3p.
From that;
P=100%.

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

Let c.p=X,s.p=2X.
The gain=2X-X=X (s.p-c.p).
And gain%=X/X*100 (gain*100)/c.p.
The gain=2X-X=X (s.p-c.p).
And gain%=X/X*100 (gain*100)/c.p.

Let the C.P be Rs.100 and S.P be Rs.x, Then
The profit is (x-100)
Now the S.P is doubled, then the new S.P is 2x,
New profit is (2x-100),
Now as per the given condition;
=> 3(x-100) = 2 x-100,
By solving, we get;
x = 200.
Then the Profit percent = (200-100)/100 = 100.
Hence the profit percentage is 100%.
The profit is (x-100)
Now the S.P is doubled, then the new S.P is 2x,
New profit is (2x-100),
Now as per the given condition;
=> 3(x-100) = 2 x-100,
By solving, we get;
x = 200.
Then the Profit percent = (200-100)/100 = 100.
Hence the profit percentage is 100%.

@ Sangeetha k.
The formula for profit % is (Profit/CP)/100.
The formula for profit % is (Profit/CP)/100.

@Bhagath.
Gain%=(Gain*100)/C.P.
65%= (x*100)/2(65%).
65% = (x*100)/(130%),
65%*130% = (x*100),
X = 8.45%.
Gain%=(Gain*100)/C.P.
65%= (x*100)/2(65%).
65% = (x*100)/(130%),
65%*130% = (x*100),
X = 8.45%.
