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 |

This question was asked in AFCAT 2/2015 and I answered 100% but when their answer sheet came out their answer was (199/3)%. I just don't get it.

Why did we taken 3(y-x) = (2y-x)? Please explain it.

Let C.P.= x, S.P = y.
Then according to the question 3(y - x) = (2y - x).
So y = 2x.
We know that, profit= (S.P - C.P).
=> (y - x) = (2x - x).
=> (x*100)/100 = 100% answered.
Then according to the question 3(y - x) = (2y - x).
So y = 2x.
We know that, profit= (S.P - C.P).
=> (y - x) = (2x - x).
=> (x*100)/100 = 100% answered.

Let cp = x., then sp = 2x.
The profit is (sp - cp)/cp * 100.
(2x - x)/x * 100.
x/x * 100 = 100.
Therefore profit =100.
The profit is (sp - cp)/cp * 100.
(2x - x)/x * 100.
x/x * 100 = 100.
Therefore profit =100.

Let CP =x and SP = y.
According to the question 3(y - x) = 2y - x.
Here in question this equation 'is given as condition only.S.P is already fixed.
This condition connects between SP and Cp from this condition we get the relation betweenSP and Cp as y = 2x .
Then we should take profit => y - x = 2x - x = x.
Thus profit % = x/x *100 = 100%.

P = S.P - C.P.
Profit triples and S.P doubles.
3P = 2S.P - C.P.
3(S.P - C.P) = 2S.P - C.P.
So, S.P = 2C.P.
S.P/C.P = 2/1.
P = 1 / 1*100.
Then, 100%.
Profit triples and S.P doubles.
3P = 2S.P - C.P.
3(S.P - C.P) = 2S.P - C.P.
So, S.P = 2C.P.
S.P/C.P = 2/1.
P = 1 / 1*100.
Then, 100%.
