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.

Gain% = 22.5; S.p =392.
C.P = (100/(100 + Gain%) * S.P).
C.P =(100/ (100 + 22.5) * 392) = 320.
So, profit = S.p - C.p = 392 - 320 = 72.
C.P = (100/(100 + Gain%) * S.P).
C.P =(100/ (100 + 22.5) * 392) = 320.
So, profit = S.p - C.p = 392 - 320 = 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.
CP =40 sp =49 given 49 = 392.

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.
(100 / 122.5)*392,

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
