Let retail price=Rs 100.
commission=Rs 10
then S.P=(100-10)=Rs 90
gain=20%
C.P=(100/120)*90
=Rs 75
new commission=Rs 15
new S.P=(100-15)=Rs 85
gain=(S.P-C.P)=(85-75)=Rs 10
gain=(10/75)*100
= 13.33%

25.45 %....let mp be marked price and cp be its cost price so
sp1= mp+mp/10 = 11mp/10 which is the sum of cp and profit..so 11mp/10=cp + cp/5=>cp = 11m/12 now sp2= m+15m/100=115m/100 so gain percent in second case = (((115m/100)-cp)/cp)*100 putting cp=11m/12 we get profit =25.45%
