Step-by-step explanation:
Let the two digit be x and y
∴ Number (2−digit) =10×x+y
Sum of 2−digit and reverse of it
⟹10x+y+10y+x=66 (given)
∴x+y=6 (equation 1)
Digits differ by 2
∴x−y=2 (equation 2)
On adding,
2x=8
⟹x=4
∴y=2
or, x+y=6 From 1 equation
and y−x=2 From 2 equation
On adding:
2y=8
y=4
x=2
∴ Two digit numbers are: 42 and 24
