minefield  (12 years ago)

since there is overflow (carried over) of y in MSB Y must be 1 because sum of 2 digit from 0,9 ranges to 0 to 18, so MSB must be 1

Now consider the lsb we have x+y+z which should be equal to 10+x because the answer of LSB addition is z. so if addition of lsb is 1z the 1 would be carried over and z would remain in the asnwer

eq1
x+1+z = 10+z => x=9

now
consider the 4th term from right
x+y+z +1 = 10+x
(+1 because carry is being taken from 3th term from right)
(same logic)
1+z+1 = 10
z = 8

ans x=9 y =1 z=8
