Hanny_b

sincerely I don't understand the way u got 20%

pls show some workings

Timothy Godspower

%gain= sp-cp/cp×100
Cp=1500
If 10 eggs were damage from the 100 eggs, we will be left with 90 eggs
Note; he sold the rest at #20 each
Therefore the SP will be
#20 = 1egg
#x = 90egg
X = 1800
That is SP for 90 eggs equal to 1800
Therefore
%gain =1800-1500/1500×100
= 20% gain.

Good one

This won't give 20 it would give 18

Therefore the SP will be
#20 = 1egg
#x = 90egg
X = 1800
That is SP for 90 eggs equal to 1800
Therefore
% gain=300÷1500×100
= 20% gain.
