The percentage profit earned by selling an article for Rs. 1920 is equal to the percentage loss incurred by selling the same article for Rs. 1280. At what price should the article be sold to make 25% profit?
Answer: Option
Explanation:
Let C.P. be Rs. x.
| Then, | 1920 - x | x 100 = | x - 1280 | x 100 |
| x | x |
1920 - x = x - 1280
2x = 3200
x = 1600
 Required S.P. = 125% of Rs. 1600 = Rs. |
 |
125 | x 1600 |  |
= Rs 2000. |
| 100 |

Profit and loss percentage equals means by formula.
Sp - cp/cp = cp - sp/cp. (100 is cancelled on both sides).
also, cancel cp on both sides then,
2cp = sp+sp
Cp = 1280 + 1920/2,
Cp = 1600.
By gain of 25%.
1600 + 25% of 1600,
1600 + 400 = 2000.
Sp - cp/cp = cp - sp/cp. (100 is cancelled on both sides).
also, cancel cp on both sides then,
2cp = sp+sp
Cp = 1280 + 1920/2,
Cp = 1600.
By gain of 25%.
1600 + 25% of 1600,
1600 + 400 = 2000.

If the percentage of profit and loss is same, the C.P. is in the middle of both selling prices so you can apply the formula.
C.P= (SP1+SP2)/2=(1920+1280)/2=1600.
Now you want 25% profit means the new S.P is 1600+25%of it.
=1600+400=2000.
C.P= (SP1+SP2)/2=(1920+1280)/2=1600.
Now you want 25% profit means the new S.P is 1600+25%of it.
=1600+400=2000.

Profit = 4:5.
Main concept;
{
In loss = cp>sp.
Loss = cp - sp.
while in profit in its ci.
vice versa,
profit = sp-cp.
}
Loss = x-1280
Profit = 1920-x
Loss = profit
2x = 3200
x= 1600
profit = 4:5.
4-----> 1600.
5-----> 2000.

Simple method :
SP:1920 at Gain of x
SP: 1280 at loss of x
Gain = (1920-1280)/2
= 320
CP : 1920-320 = 1600
Now,
Gain is 25%
25= Gain*100/CP
Therefore
Gain = 25*1600/100= 400.
SP for Gain 25% is CP+gain = 1600+400= 2000.
SP:1920 at Gain of x
SP: 1280 at loss of x
Gain = (1920-1280)/2
= 320
CP : 1920-320 = 1600
Now,
Gain is 25%
25= Gain*100/CP
Therefore
Gain = 25*1600/100= 400.
SP for Gain 25% is CP+gain = 1600+400= 2000.

Earned profit on selling at 1920 = beared loss on sold at 1280.
There sum= 1920+1280=3200,
So the base price is with no profit no loss=3200/2=1600,
To make a profit of 25% on 1600=1600*25/100=400,
So total =1600+400=rs 2000.

Let C.P be Rs. x.
Then ((1920-x)/x)*100 = ((x-1280/x)*100.
1920-x = x-1280.
2x = 3200.
x = 1600.
Required S.P = 25% of RS.1600 = ((25/100)*1600) = 400.
From 1600 25% profit means,
(1600+400) = 2000.
Answer: Rs. 2000.
Then ((1920-x)/x)*100 = ((x-1280/x)*100.
1920-x = x-1280.
2x = 3200.
x = 1600.
Required S.P = 25% of RS.1600 = ((25/100)*1600) = 400.
From 1600 25% profit means,
(1600+400) = 2000.
Answer: Rs. 2000.

If profit on condition 1 and loss on codition 2 is same
then, cost prise=1280+1920/2
=1600
after that on 25% profit=1600*125/100
=2000
that prove that c is the ans.
then, cost prise=1280+1920/2
=1600
after that on 25% profit=1600*125/100
=2000
that prove that c is the ans.

let, x=profit.
The percentage is always calculated base upon the cost price.
so, 1920-x=1280+x,
x=320.
cost price=1280+320=1600,
Gain = 25*1600/100= 400.
SP for Gain 25% is CP+gain = 1600+400= 2000.

Its very simple questions profit incrd when selng it at 1920 is same as los when sel it at 1280 take average of two .i.e .1920+1280/2=1600 is new cost so prf 25%of 1600=400.so add 1600+400=2000

Profit = SP-CP,
LOSS = CP-SP,
SP-CP = CP-SP,
SP+SP = CP+CP,
1920 + 1280 = 2CP,
3200/2 = CP.
1600 = CP.
SP = %PROFIT* CP.
SP = 100+25/100 * 1600,
SP = 125/100 * 1600,
SP = 2000.
LOSS = CP-SP,
SP-CP = CP-SP,
SP+SP = CP+CP,
1920 + 1280 = 2CP,
3200/2 = CP.
1600 = CP.
SP = %PROFIT* CP.
SP = 100+25/100 * 1600,
SP = 125/100 * 1600,
SP = 2000.
