CP = 90/100 * SP
Profit % = (SP - CP)/CP * 100 = [ SP/CP - 1 ] * 100
= [ 100/90 - 1 ] * 100 = 11.11
%
=============
SP = Rs 750
Gain = SP - CP = CP/9
SP = CP (1+1/9)=10*CP/9
= Rs 750 => CP = Rs 9*75
Gain % = Rs 75/(9*75) * 100 = 11.11%
==========================
15 * CP = SP * 20 = (CP - Loss) * 20
5 CP = 20 * Loss
Loss = CP/4
Loss % = CP/4 )/CP * 100 = 25%
=============================
250 * (SP - CP) = total gain = 25 SP
9 SP = 10 CP
Gain % = (SP - CP)/CP * 100 = [ SP/CP -1 ] * 100
= 100/9 %
============================
Gain in selling one toffee = SP - CP = 1/5 - 1/6 = 1/30
gain % = (1/30) / (1/6) * 100 = 20%
