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 |

1920 + 1280 = 3200.
Half is 1600.
Profit is 25%.
1600 * 125/100 = 2000.

Let ;
cp = x.
sp for profit = 1920.
profit = 1920-x.
sp for loss = 1280.
loss = x - 1280.
atq-
(1920-x)=(x-1280).
further by solving x = 1600.
So sp = 1600.
Now for 25% gain 25% = 1/4.
25%of 1600 = 400.
Now sp for 25% gain.
= 1600 + 400 = 2000 answer.
cp = x.
sp for profit = 1920.
profit = 1920-x.
sp for loss = 1280.
loss = x - 1280.
atq-
(1920-x)=(x-1280).
further by solving x = 1600.
So sp = 1600.
Now for 25% gain 25% = 1/4.
25%of 1600 = 400.
Now sp for 25% gain.
= 1600 + 400 = 2000 answer.

Simple way:
Our motive is to find sp so sp(formula) = 100+profit%/100*cp
But we are not having CP.
So, as this problem dealt with profit %.
So, cp = 100/100 + profit% * sp(sp = 1920 as in question mentioned only profit % so leave loss%)
cp = 100/100 + 25 * 1920 = 1600.
Now sp = 100 + gain%/100*cp
= 100+25/100 * 1600.
= 125 * 16.
= 2000(final ans).

cp = 100/100 + 25 * 1920 = 1600.
Now sp = 100 + gain%/100*cp
= 100+25/100 * 1600.
= 125 * 16.
= 2000(final ans).

@All.
Here is my solution:
Solution:
Step 1: 1920 − CP = CP − 1280.
Step 2: 2CP = 3200,
Step 3: CP = 1600,
Step 4: For 25% profit → ratio = 4 : 5,
Step 5: 4 parts = 1600 → 1 part = 400,
Step 6: SP = 5 × 400 = 2000.
