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 |

since profit(P) and loss(L) percentages are same:
=> P% = L% => P = L .
S.P for P% =1920 ; S.P for L% = 1280
=> 2P =2L = 1920 -1280 = 640
=> P = L = 320
Therefore C.P = S.P(p) - P = S.P(l) + L = 1600
new selling price for 25% profit will be
S.P = ((100 + P) / 100) * C.P = ((100 + 25) / 100) * 1600
= 125/100 * 1600
= 2000
=> P% = L% => P = L .
S.P for P% =1920 ; S.P for L% = 1280
=> 2P =2L = 1920 -1280 = 640
=> P = L = 320
Therefore C.P = S.P(p) - P = S.P(l) + L = 1600
new selling price for 25% profit will be
S.P = ((100 + P) / 100) * C.P = ((100 + 25) / 100) * 1600
= 125/100 * 1600
= 2000

Profit=sp-cp=>1920-cp.
Loss=cp-sp=>cp-1280.
Profit percentage = loss percentage(given).
1920-cp = cp-1280,
cp = 1600,
25% of cp = 400.
Therefore, sp=1600 + 400 = 2000.
Loss=cp-sp=>cp-1280.
Profit percentage = loss percentage(given).
1920-cp = cp-1280,
cp = 1600,
25% of cp = 400.
Therefore, sp=1600 + 400 = 2000.

Explain ((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.

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

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

Loss, = (s.p- c.p( loss)/ c.p) * 100.

Loss percentage means (loss/s.p)*100 but in solution you took (loss/c.p)*100 how come?
Please explain.
Please explain.

(1920+1280)/2 = 1600,
(1600/100) * 25% = 400,
1600+400 = 2000.
(1600/100) * 25% = 400,
1600+400 = 2000.
