s = selling price of 1 article
c = cost price of 1 article
10s = 11c
s = 1.1c
The gain of 1 piece:
g = s - c = 1.1c - c = 0.1c
The gain percent:
g / c = 0.1c / c = 0.1 = 10%
c = cost price of 1 article
10s = 11c
s = 1.1c
The gain of 1 piece:
g = s - c = 1.1c - c = 0.1c
The gain percent:
g / c = 0.1c / c = 0.1 = 10%
