Question 702073
let the two digit no is 10x+y
The units digit of a two digit number is 2 less than the tens digit.
so y=x-2..........1
The number is 2 more than 6 times the sum of the digits. 
10x+y=6(x+y)+2=6x+6y+2
or 4x-5y=2....2
putting the value of y from 1
4x-5(x-2)=2
or 4x-5x+10=2
or -x=2-10=-8
or x=8
from 1 
y=8-2=6
so the no is 10*8+6=86
