Always remember that If the value of a no. is first increased by a% and later decreased by a %,then the net effect is alwaysa decrease which is equal to a% of a and is given by 
(a^2/100)% or (a^2/10) % 


coming to ur question, 
a=10% 

acc. to formula, nw u knw tht change in the salary of gopal is a decrease. 
therefore, decreased % tage= 10^2/100 % =100/100 % =1 %

hope it helps !!
