Hello student,
Let the unit digit be X and ten 's digit be Y. So, original digit be ( X+10.Y) , And by reversing the digit we get (Y+10.x)
SO ACCORDINGTO THE QUESTION
(X+10Y)+(Y+10X) = 66
11X+11Y = 66
11(X+Y) = 66
X+Y = 66/11
X+Y = 6 ------------------- 1
And, since digits differ by 2
So, X-Y = 2 --------------- 2
Adding 1 and 2 equations we get
2X = 8
X = 8/2
so, X = 4
And, puttingvalue of Xin equation 1
X + Y = 6
4 + Y = 6
Y = 6 - 4
Y = 2
Therefore, number is given by putting value of X & Y
Hence, number is ( 4+10*2) = 24...
There are manysuch numbersdepending on equation!
Thanks and Regards
