5+5+x(1-90%)=260
10+x(10%)=260
x=(260-10)*10/1
x=2500
or
X(10%)=260-5-5
X=250/(10%)
X=250(100/10)
X=250*10
X=2500
or
10+x(10/100)=260
x(10-100)=250
x=250(100/10)
x=2500
10+x(10%)=260
x=(260-10)*10/1
x=2500
or
X(10%)=260-5-5
X=250/(10%)
X=250(100/10)
X=250*10
X=2500
or
10+x(10/100)=260
x(10-100)=250
x=250(100/10)
x=2500
