Now, as given tens digit is 2 greater than the unit digit.
∴
Next, the hundred digit one greater than the tens digit.
∴
The sum of the tens and the hundreds digits is three times the units digit.
∴
Now, substituting the value in the equation.
⇒
solving it to get value of y
⇒
⇒
∴
Next, finding value of z
y=
substituting the value of y and subtracting both side by 2
∴ z=
Last, finding the value of x
substituting the value of y
∴ x= 8
xyz= 875
