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 |

When we should assume CP as some numeric value and as unknown value like 'x'.

Please simplify.
1920-x/x*100=x-1280/x*100.
1920-x/x*100=x-1280/x*100.

@Buk.
Just eliminate the denominator x and the 100 you will get this result.
1920-x=x-1280 then you will able to get it.

Explain ((1920-x)/x)*100 = ((x-1280/x)*100.

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.

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.

1920-1280 = 640.
640/2 = 320.
1280+320 = 1600.
1600*(25/100) = 400.
1600+400 = 2000.
640/2 = 320.
1280+320 = 1600.
1600*(25/100) = 400.
1600+400 = 2000.

(1920+1280)/2 = 1600.
For 1600 25% is 400.
So 1600+400 = 2000.
For 1600 25% is 400.
So 1600+400 = 2000.

X%=1920-y)*100/y ---> (1)
X%=(y-1680)*100/y ---> (2)
Were x=profit and loss %.
And y=CP.
ACC qu (1)=(2).
So we get CP y=1600.
Then SP = y+y of 25%===2000.
X%=(y-1680)*100/y ---> (2)
Were x=profit and loss %.
And y=CP.
ACC qu (1)=(2).
So we get CP y=1600.
Then SP = y+y of 25%===2000.
