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%
