Let the no. be xyz
x+y=10
Its value is 100x+10y+z
(100x+10y+z)÷×=108
100x+10y+z=108x
100x-108x+z=10y
-8x+z=-10y......(i)
(100x+10y +z)÷(x+y+z)=36
64x-26y-35z=0
64x-35z=26y......(ii)

(-8x+z=-10y)35
(64x-35z=26y)1
-280x+35z=-350y +
64x-35z=26y
÷-216(-216x=(-324y)÷-216
        x=1.5y
x+y=10
1.5y+y=10
2.5y=10 
y=4 
x+4=10
x=10-4
x=6
64x-35z=26y
(64×6)-35z=(26×4)
384-35z=104
384-104=35z
280=35z 
z=8
The no. is 648
