A shopkeeper expects a gain of 22.5% on his cost price. If in a week, his sale was of Rs. 392, what was his profit?
Answer: Option
Explanation:
| C.P. = Rs. |  |
100 | x 392 |  |
= Rs. | |
1000 | x 392 | |
= Rs. 320 |
| 122.5 | 1225 |
Profit = Rs. (392 - 320) = Rs. 72.

cp =100 profit =22.5
sp =100+22.5 =122.5.
122.5 -------------> 22.5
392 --------------> x.
(392|*22.5)/122.5 = 72.
sp =100+22.5 =122.5.
122.5 -------------> 22.5
392 --------------> x.
(392|*22.5)/122.5 = 72.

Fraction 22.5/100 = 9/40.
CP =40 sp =49 given 49 = 392.
1 unit = 8
So cp 40 * 8 = 320.
392 - 320 = profit.
72.

I think this the formula for the first step;
Cp*(100 +Profit or Loss% / 100) = SP.
Therefore, CP = SP*100/(100 + Profit or loss%).
Cp*(100 +Profit or Loss% / 100) = SP.
Therefore, CP = SP*100/(100 + Profit or loss%).

(100 / 100+22.5) *392,
(100 / 122.5)*392,
(1000/1225)*392.
320.
To remove the decimal in the denominator the numbers 100/122.5 were multiplied by 10 in both the numerator and denominator.

P = C × 0.225 and
C = 392/1.225 = 320.
Thus S = C + P.
P = 320 * 0.225 = 72.
C = 392/1.225 = 320.
Thus S = C + P.
P = 320 * 0.225 = 72.

Profit=22.5%. and SP=392
Then CP * 122.5/100 = 392.
After solve we get CP = 320,
Now simple (sp-cp) = 72.
I think it will help you.
Thanks have a great day.

Can anyone explain me what formula used and how get 122.5?

@Ragav.
Basic formula is cost + profit = selling price.
Here we assume cost is 100. given profit is 22.5%.
CP + P= SP Which means 100 + 22.5 = 122.5.
So, we get SP 122.5 which is 392.
122.5 = 392
22.5 = x
Just cross multiply it you'll get the answer.
