Profit%= s.p - c.p/ c.p.
Let x be the cost price.
Here profit %= 22.5.
S.p = 392 is given.
According to formula.
22.5/100= 392.
22.5x = 39200 - 100x.
122.5x = 39200.
X = 39200/122.5.
X = 320.
So, c.p is Rs 320.
Now finding profit.
Profit = s.p - c.p.
Profit = 392 - 320.
Profit = 72.
Let x be the cost price.
Here profit %= 22.5.
S.p = 392 is given.
According to formula.
22.5/100= 392.
22.5x = 39200 - 100x.
122.5x = 39200.
X = 39200/122.5.
X = 320.
So, c.p is Rs 320.
Now finding profit.
Profit = s.p - c.p.
Profit = 392 - 320.
Profit = 72.

Gain =22.5% on C.P.
S.P=392 Rs.
Let C.P be Rs x.
Gain%= ((S.P-C.P)/C.P)*100.
((392-x)/x )*100 = 22.5.
x=320 rs.
Profit= S.P - C.P = 392-320 = 72 Rs Ans.
S.P=392 Rs.
Let C.P be Rs x.
Gain%= ((S.P-C.P)/C.P)*100.
((392-x)/x )*100 = 22.5.
x=320 rs.
Profit= S.P - C.P = 392-320 = 72 Rs Ans.
