Let C.P = x.
Therefore,
S.P = 22.5% of x + x.
=> (22.5/100) *x +x.
=> x((225/1000)+1).
=> x((9+40)/40).
=> 49x/40.
Acc to question,
(49x/40) = 392.
x = 15680/49.
x = 320.
Therefore, profit = 392 - 320.
=> 72 Ans.

Given S.P = 392, expect profit = 22.5%
Let us take C.P = 100.
C.P = (C.P/S.P)*S.P.
S.P = 122.5(EXPECTS).
C.P = (100/122.5)*392(real).
C.P = 320.
P = 392-320 = 72.
Let us take C.P = 100.
C.P = (C.P/S.P)*S.P.
S.P = 122.5(EXPECTS).
C.P = (100/122.5)*392(real).
C.P = 320.
P = 392-320 = 72.

1225 = 3920.
100 = ?
? = (3920*100)/1225.
C.P = 320.
So profit = 392-320.
= 72 Rs.
100 = ?
? = (3920*100)/1225.
C.P = 320.
So profit = 392-320.
= 72 Rs.

Simple one.
22.5% = 9/40 which means there is a profit of 9 over 40.
So Cp = 40.
Sp = 49.
P = 9.
But in question Sp = 392 i.e. 8 times of 49.
So P = 9x8 = 72.
22.5% = 9/40 which means there is a profit of 9 over 40.
So Cp = 40.
Sp = 49.
P = 9.
But in question Sp = 392 i.e. 8 times of 49.
So P = 9x8 = 72.

C.P = (100sp)/(100+p).
>>100*392/122.5 = 320.
>>profit = 392-320 = 72.
>>100*392/122.5 = 320.
>>profit = 392-320 = 72.

If cost price = 100 sell price = 100+22.5 = 122.5.
If selling price is 122.5 then profit 22.5.
.............. 1 ......... 22.5/122.5.
.............. 392 ....... (22.5*392)/122.5 = 72.
If selling price is 122.5 then profit 22.5.
.............. 1 ......... 22.5/122.5.
.............. 392 ....... (22.5*392)/122.5 = 72.

Let x is the cost price:
x*22.5/100 = 392-x.
x*22.5/100 = 392-x.
