Step-by-step explanation:
The sum of a two digit number and the number obtained by reversing the digit is 66 if the digit of the number differ by 2 find the number how many such numbers are there
Let say NUmber is XY
Value = 10X + Y
Reverse of number = YX
Value = 10Y + X
10X + Y + 10Y + X = 66
=> 11X + 11Y = 66
=> X + Y = 6 - eq1
|X - Y| = 2
Case 1
X - Y = 2 - eq2
Adding eq 1 & eq 2
=> 2X = 8 => X = 4 & Y = 2
Case 2
X - Y = -2 eq 3
Adding Eq 1 & eq 3
=> 2X = 4 => X = 2 & Y = 4
Numbers are 42 & 24
& reverse of numbers are 24 & 42
