Answer:
Let the two digit number be 10x + y where
y is units digit and x is ten's digit.
It is given that
x = 2y + 2 ... (1)
and 10y + x = 3(x+y)+5.... (2)
an solving equation (2) and (1)
10y + x = 3x + 3y + 5
⇒ 7y-2x = 5
.. 7y - 2(2y + 2) = 5
3y -4=5
3y=9
y = 3
and x = 2y + 2 = 6+2=8
the two digit number is 83
